[POTKU] New Potku versions for mac and windows

[Laitinen, Mikko]

Dear All,

please see the

or direct download page:
https://www.jyu.fi/science/en/physics/research/infrastructures/accelerator-laboratory/pelletron/potku/release_versions

for the newest ToF-ERD software version of the Potku.

Below is a short description for some of the updates, and the ones now in the pipeline.
More details from https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FJYU-IBA%2Fpotku&data=04%7C01%7C%7Cdf8dcc993c944d0dae0808da13b8e362%7Ce9662d58caa44bc1b138c8b1acab5a11%7C1%7C0%7C637843982051008295%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=JxAukFRQD7GYd2Bb0owCIHdN4edrGCpNC0McbOE1%2BaM%3D&reserved=0
and if interested, one can see the currently known and to be worked issues from https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FJYU-IBA%2Fpotku%2Fissues&data=04%7C01%7C%7Cdf8dcc993c944d0dae0808da13b8e362%7Ce9662d58caa44bc1b138c8b1acab5a11%7C1%7C0%7C637843982051008295%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=X%2BYwBEmPO%2FDjBXFIamtYNGH0UEBkQ%2F%2F6OR2h5m%2Bcq34%3D&reserved=0

31.3.2022 Mac and windows versions

New release of both Mac and Windows versions dated 2022-03-31 can be found from here.
Note: Window 10 and new MacOs warns about these programs (without the authentication "stamp"), as "do you want to still Run this program (Potku.exe)".

This update has made lot of internal upgrades but now also offers
- plotting and storing the sum of the individual energy spectra in the slab analysis as well as sin the MCERD
- faster automated (linear) optimization available in the MCERD. This is test version, but can already be used. The previous, still existing NSGA-II (evolutionary multiparameter code) was way too slow for the purpose.
- Usability features for the MCERD side, including:
** Target composition is now directly exported to  the recoil atom distribution and modifications of target atom composition are  now taken into account
** Yellow indicators for individual recoils/scatter atoms if non-default values are activated by the user
** User can delete all recoil atom distributions at the same time

Something coming soon, work already in progress:
- Improved speed for the slab analysis cut files saving and while doing the selection
- Possibility to import single cut file to the ToF-E historgram
- Possibility to modify the selections, by dragging the points of the cut
- Important one: automated calculation of the "Reference density", for the MCERD, side (this value affects the depth scale, together with the density and composition of the target),
- Python version upgrade from 3.6 to 3.10(or 11)


In the Potku email list, there are now bit more than 40 addresses, from about 15 different sites. If you have potential students, or senior members, in your mind - to remind them also about the Potku, please feel free to forward this message.
Here is also the direct link for the subscription of the email list:

I have been quite busy in the past year (more projects going on than personnel hours), but I will soon try to announce the earlier promised MCERD training session/webinar. Apologies for this being delayed.

Best regards from sunny, no clouds, -10C, Jyväskylä!
