Re: Red Pitaya MCA

You are using a positive input? What about your baseline?
Mine was set to automatic baseline.... I think there is some quirkiness to this software due to Java.

What will you use for the HV supply?

Re: Red Pitaya MCA

Using the Gamma spectacular as a HV source and an iRad labs splitter the incoming voltage is right within the 0-1V range and works (as you've suggested) The first program ( the one you are showing here, MCA) is written by a local astrophysicist, Will Thompson who lives/lived in Victoria B.C. btw, ho...

Re: Red Pitaya MCA

Both programs have source codes on Github and are 100% modifiable. The author of the last program -MCPHA doesn't seem to understand wanting scalable bins and argued with me about not adding such a function in. He is under the impression that 16K bins is better than 4096 or 2048.... Anyways, maybe we...

Re: First Test of SiPm Detector

Wow, that is super cool! Very good efficiency for that tiny a crystal. I wonder what would happen you coupled the output to a RedPitaya?

Re: Unknown uranium mineral found in Penticton B.C. while on holidays

Ok, so I have just had an hour long conversation with the head geochemist with the BC Govt. regarding my find. Basically, my find is to be expected as relatively young Uranium and Thorium deposits are quite common in the entire interior (Okanagan) region, I kind of knew that already (obvious)... how...

Re: Unknown uranium mineral found in Penticton B.C. while on holidays

Well I have a number of other places to go find Uranium minerals in BC. I hope I am able to make another trip before the start of School... There is a major Uraninite, Zeunerite/meta zeunerite and Thorianite deposit in Lytton that I have been meaning to find. I tried last year and was close enough t...

Re: Unknown uranium mineral found in Penticton B.C. while on holidays

The Scionix Holland NaI/Tl probe is the one I purchased from you last March/April. It has been indispensable when trying to identify Th or U minerals and has quite high resolving power. I also took one of your plastic scint. probes with me on my hunt, again it allowed me to quickly zero in on the de...

Unknown uranium mineral found in Penticton B.C. while on holidays

Just got back from a week long vacation into wine country here in BC. Day we arrived was during an end of a 4 week long heat wave that saw temps in the 38-46c range. On the second to last day I decided to use my Minfile map and try and located the mysterious Thorium deposit recorded back in 1977. It...
