I'm dead tired right now... After I held my talk yesterday (outfit above; trying to "be me" but just enough "conservative" at the same time) I felt like I just collapsed (I managed to take part in the conference dinner, luckily 😛 ), and this morning I just slept through my alarm - which never happens, except maybe if my body is trying to tell me a needed a couple of extra hours sleep. I've been really stressed about the talk yesterday, and the (preliminary) results that I showed was finished on Wednesday afternoon. Being so "last minute" didn't exactly feel great, and that was probably one reason why I was so nervous.
It has been a great week though; and even if I really  just want to go home now, and go to sleep, I'm going out with all my great nuclear physicist colleagues from all over the world <3
Wishing everyone a great Friday and a great (long) weekend!

My talk is tomorrow.
It's not finished yet.
I feel nervous, but also excited...
Nervous, because I wish I had come further than I have, and that I understood "everything". Excited, because I actually do have results, and they are nice, and they make sense. They make me believe that I will actually do this; not just the talk tomorrow, but I will finish my next paper (article/publication) in June (or maybe July - but hoping for June). After that I will start directly to analyse the second part of the uranium experiment, and hopefully it will be much "easier" since I have already done it once 😉 
I'm in my bed right now, working on the presentation for tomorrow, which is around 11. Think I will work for around 30 more minutes, and then go to sleep. I'd rather get up at 5 tomorrow morning, and finish it then.
Wish me luck <3

Good morning everyone <3
I'm at the University, attending the second day of the "5th Workshop on Nuclear Level Density and Gamma Strength" - the conference/workshop that our research group is arranging. Nuclear Level Densities and Gamma Strength (Functions) are fundamental properties of the atomic nucleus, and they are sort of the main goal of my data analysis just now.
I think my favourite talk so far was the one called "Neutron capture cross sections for the astrophysical r-process" by professor Artemis Spyrou from Michigan State University. Nuclear astro physical applications are really exciting <3 Unfortunately I missed the first talk this morning (stupid rain), which was by Luciano Moretto - I really regret this, because he always gives great talks...:/
Anyway; I'll be spending the rest of the week in this same auditorium, listening to talks - together with around 60 other nuclear physicist from around the world (West Coast of US, South Africa, and India, for example 🙂 )
I just realized that a hashtag has occured; #oslogamma! I don't think it will be the most popular hashtag on twitter, but at least it's there, if you want to follow 😉
Ok, now I have to pay close attention to all the talks - or, if there's something I don't understand ANYTHING of, I need to prepare my own talk that I'm giving on Thursday. Also, I need to work more on the actual analyzis of my data, so that I have more than just one plot to show...that would be a very short talk 😉

I'm so relieved right now...! It turns out I've (probably) done a good job when I've calibrated my gamma detectors - and now I'm actually getting real results.
It's preliminary, of course, but it's there - something I can actually show in my talk at the conference here in Oslo next week (that I've been so nervous and stressed about :/ ).
There is still tons of work to do, but I must admit I'm really happy and motivated for everything right now; nothing can stop me, and the rest of 2015 will be about analyzing data and writing papers...<3<3<3
-------------------------------------------
Here are some happy pictures from yesterday (spending a day off with Alexandra) and todays celebration of 17th of May in kindergarden - just love Biørneblæs, the student marching band!

Happy weekend and 17th of May (for those of my readers that celebrate such things) and everything!
TGIF <3

...in several ways...

Finished with the calibration of the gamma detectors (happyhappyhappy 🙂 ), but now I'm also "finished" mentally :/
Started this day by oversleeping (not the best start of a looong day), then I gave a talk about nuclear power and radiation at the biology department, and after that I've been working at Gry's office (she helps me A LOT <3) and my own office.
me, ready (sort of) for talking to the biology students - wearing one of my favourite dresses from HM, and of course heels  
After spending a couple of hours fine tuning my gamma detector calibration, I made this plot - showing gamma radiation from oxygen and beryllium. It looks like the peeks are only 20-30 kilo electronvolts "off", and I think that's ok (I'll ask someone with much more experience than me tomorrof, of course!).
---------------------------------------------------

So now I've started to look at time correction stuff - having "fun" with staring at these different graphs. If they look the same, I can tell you they're not, but it's definitely not easy to see which one is "best". At least not for me...
After a good night's sleep it will probably be clearer when I can discuss this with someone (Supervisor Sunniva? 😉 )  tomorrow - meaning; I've been at the University for 12 hours, and now it's time to go home <3

...it's starting to look like something (I hope...).

In the plot are the two beryllium-peaks that I have used for the calibration - the first one is supposed to be at an energy equal to 3.368 mega electronvolts (of energy), and is now placed at 3.399 mega electronvolts, and the other one is supposed to be at 5.96 mega electronvolts, but is at 5.97:

The error is less than 1%, so it's not too bad - but I have to see what Sunniva has to say tomorrow...hope she approves 😉
Anyway; I can "tick off" my main goal for today - to get the gamma detectors calibrated. There are probably adjustments that have to be made - for example, there's something strange with the low energy gammas, since I suddenly don't get anything from oxygen-17 anymore - but this is the best I can do today. 
Now it's time to get home, and prepare for tomorrows talk about nuclear power and radiation and thorium. 9 AM in the biology building - open to everyone (and there's free breakfast 😉 )!

Not even a teeny tiny step for mankind.

(Possibly) a small leap for me - today I did this <3

This means that I've (probably) figured out the gamma radiation, well enough so that I can calibrate my gamma detectors - and then figure out the rest (*playing puzzle*). I'll know more tomorrow...
I'm quite satisfied, though, since I'm really moving forward - even though I'm moving forward one very small step at the time 😉

-----------------------------------------------------------

PS: Check out the new page I made for Sushi and Nuclear 😀

PPS: For my fabulous Norwegian speaking readers; the talks from yesterday's "Women in Tech" conference can now be seen HERE - so proud that I was part of that event!

Publisert Legg igjen en kommentar til Stressed…
I admit it; I'm feeling stressed.
Our nuclear physics workshop/conference here in Oslo, where I'm supposed to give a talk (and show RESULTS) is only three weeks away, and my gamma detectors are not yet calibrated. Don't get me wrong: it's not like I'm giving up (I don't think I'm a quitter), but I know there is work to be done. I think I have to go through my plan, and check how I'm doing with my milestones/goals - I'll give you an update tomorrow <3
--------------------------------------------------

I think I could have worked faster, but I really really want to understand this - and make sure I make NO MISTAKES! So today I made this table, and the next step is to try to find the different gamma energies from the table and place them in the plot...hope my "prework" will pay off, and that tomorrow will be successful day 😉

Good morning from the airport everyone!

I'm blogging from the gate at Gardermoen airport - on my way to Trondheim to give a talk about nuclear power (it will actually be more like two talks: one about "myths" about nuclear power and radiation, and one more technical about thorium as a nuclear fuel) for a bunch of science teachers *excited!* 😀
Just "stopping by" to say Hi, and wish you all a great, sunny (at least the weather is beautiful here at Gardermoen) day, and to tell you about the talks I'll be giving before summer - in case anyone's interested in coming 😉
  • May 6th: The "Women in Tech"-conference 
  • May 12th: Popular talk about nuclear power and maybe some thorium
  • Week 21: About the progress of my uranium-233 experiment - at the Oslo (nuclear physics) Workshop
  • May 26th: The future of nuclear power and thorium and what's really "the thing" about Norwegian thorium - INSEAD Alumni 
  • June 1st: Popular talk about nuclear power and thorium
So if you're interested, the two talks in pink are open to everyone...;)

Publisert Legg igjen en kommentar til Q-value
Today I've made this table (with my new favourite: this calculator 😀 ):
So this beautiful table shows the different Q-values for the different reactions that go on in my experiments (oh, yes, there's beryllium and there's carbon and there's oxygen there - even though it would've been nice if it was only uranium...).
The Q-value tells how much energy that is released in a certain reaction: for the first reaction, for example, the Q-value is 4620 keV, which means that when a deutron hits a uranium-233 nucleus, and a proton goes out of that reaction, around 4600 keV (energy) is released ;). If that same deutron hits an oxygen-16 nucleus instead of the uranium-233, and a triton (instead of a proton) is released, the reaction absorbs energy instead of releasing energy: 9406 keV to be (almost) exact...
I also, finally, submitted my application about changing my theoretical curriculum for my PhD degree 😀
----------------------------------------
It's beautiful at the University these days, btw - don't you agree? Love blossoming cherrytrees:)
