Re: Hello from Brian in Chicago

Hi Brian, I don't know what for a detector and a PMT inside you have, so I can not say for sure, but 1400V could be quite high. It is good for the PMT to always use the lowest possible voltage that gives linear output. Check this topic from Steven about how to determine it (it needs just what you ha...

Re: Reflectors in scintillators

That will surely be interesting for many others (including me) too Luuk, go for it ;) I don't plan to do it, but definitely it would be nice to know more about it.
Greetings and thanks,

Re: Cs137 in biomass pelletized wood ash

Thank you for your answer Ciro. I also meant the approximate activity of course, it is not that easy to determine it corectly.

Re: Making your own plastic scintillators

Hi Lukas,
Nice project indeed. I'm not going to try this for now, but I am going to cast some things in epoxy resin, so could you please tell me where did you get the mold you use and which resin you used?

Re: Studies, Jobs and the likes

Well, since this is closed commercial science I don't know enough to really be able to comment their work, but from what I've just seen in the media, I think that none of the advances they speculate with are comming anytime soon. Brain-computer interface is something that lots of scientists work on,...

Re: Any Stereo Microscope Users?

The DSLR worked well enough for me, but every setup have it's optics and different quality, maybe this is not the best option in your case. Please, tell later if the diaphragm helped.

Since early childhood my interests were always somehow divided between two scientific spheres - biology (my mother's field) and technics (my father's one). Anyway, I ended up studying veterinary medicine and later got a PhD in neuroscience in Germany. Now I work in an experimental neurosurgery in an...
