Re: What is this?

I misread your previous message, that's Massive. Most of what I want to start doing in the hobby was soil sampling. So well type detectors are not a bad idea. James. With soil, you could also use a marinelli beaker and a more conventional detector. I was hoping to use this big one for individual Tr...

Re: What is this?

Huh, didnt know you purchased one previously. So it's a 3x3 crystal, is the well so big because of sheilding? That makes more sense, I would love to pick one up with a beta detector as well. Although that's honestly a weeks pay if I didnt grind my arse off working that week. I'll be taking a look a...

Re: What is this?

Yes, the big side is a NaI crystal with a 3" PMT. The small side is a beta detector. I assume you put the sample in the well, put the beta detector on top of the sample, and you collect gamma and beta counts at the same time. I bought one of of the big well detectors, but it didn't have a beta dete...

Re: What is this?

It looks like a big well detector (duh) with a second one to close the hole. The second detector looks like a regular NaI, but mounted the wrong way round? I don't know of any application where it would make sense not to put a reflector on scintillator, apart from alpha counting of course. I'm just...

Re: Instrument cables.

Pavel, The issues I've come across was not what type of cabling needed, but rather where to buy. I tend to not trust ebay after a few cables came as a dead short. From two unrelated sellers. Most of my instruments are bnc to bnc, from meter to probe. Although I use a few eberline meters that use a m...

Re: Instrument cables.

James, I bought a couple of 1 m BNC X BNC cables from this ebay seller. I thought the quality and price was good. He might be able to get different connections. Not sure. 324181797207 I saw that listing, more I think about it I might as well go for them. I could always ask if he has other types of ...

Instrument cables.

Hello all, I've asked this on the fusor forums, but the people here seem to be more active then on fusor. Anyone have a good supplier for quality cables. I'm aware this often isnt a cheap affair. Of course a lesser price than usual is always nice. I'm now starting the search once more for cables, an...

James,
if you need mu-metal I always have some used shield for a hobby price, if you are interested send me a pm with your needs.
Than I can look if I have something for you.

Thank you Luuk, once I get time to sit down I'll see the size I'll need for the probe I'm thinking of building.
