Place the wired SiPM against the scintillation block with some optical silicone grease and wrap it tightly with PTFE tape, make sure you have multiple layers if PTFE tape. The tape not sticky but once you have a few turns it will hold. Then package the whole thing in aluminum foil sticky tape makin...

Kailie - Drilling would cause some interference with internal reflection, but I think the impact would be small. Using a good permanently clear epoxy for mounting purposes is an alternative, but that may have its own issues. If something goes wrong, it could be a mess to correct. Compression wrappin...

Kailie - Great question... The purpose of the foil wrap recommended in the CosmicWatch project is to increase internal reflection and block external light. Foil is a simple, quick and effective way to accomplish this, but not necessarily the best reflector of the internal scintillations. Foil also e...

Hi Kailie - Hope this site is able to broaden your curiosity of charged particles and deepen your understanding of the world of physics. We look forward to your contributions. Cheers, Tom

Nice work Anthony.

With all the money at stake, I would have thought advanced borehole spectroscopic logging tech would be far more common.
Glad to see your already putting that detector to good use.

Cheers, Tom

Hi Klaus - Welcome to Adventures in Wonderland... ;-)

Beryllium can be problematic (even hazardous) to work with. It is also prone to corrosion, very expensive, and difficult to find. It is rarely used for more than "window" material at the front of a probe used for very low energy. It would only be useful if you had a PMT and crystal assembl...

Hi Paulo Your question and stated reasons cause me to think you are questioning the housing design for the entire detector, not just the PMT (Photomultiplier Tube). Your reasonings mostly fit both uses, the PMT housing and the Crystal can portion of a detector. Often these are made of the same mater...

Welcome Yosef! We look forward to your participation on the forum for many years to come.
