Oh!
I knew that SrI:Eu had the trailing edge in its spectrum, but I didn't know that longer collecting time did the trick to reduce it!
Please open a thread on this macropixel, that would be a very interesting collection of information.

Re: Red Pitaya MCA
That looks nice. I really like the small CsI for 415$ and the Cs2LiYCl6 for 765$ if you cant afford 3% resolution, you could get 4.5% for 500$ less :DRob Tayloe wrote: ↑19 Nov 2020, 06:12The folks at CapeSym let me know that it is now possible to order on-line at the link below:

The CsI one would be really cool to use in a portable device

Re: Red Pitaya MCA
I just made a modification to the Red Pitaya MCA program to add more options for bins.
We now have 1028,2048,4096,8192 and 16K bin options available.
Modifications below in code. You will need to modify the index.html file in the MCA folder.
