More fun with CeBr3

[Sesselmann]

I just finished a nice detector for a customer with a 1.5" x 1.5" CeBr3 crystal, and unfortunately I have to ship it out tomorrow, but before I do, I like to share the spectrum with you.

The resolution of CeBr3 is slightly lower than LaBr3, but it doesn't suffer from the internal noise, which I think makes it a better detector.

The detector is built with a 2" Hamamatsu PMT and it came in at a not so shabby 4.2% with the GS-USB-PRO.

Once again like LaBr3 it's hard to justify the cost of this detector, but certainly a pleasure to work with.

Hi Steven,
4.2% with a standard pmt is very nice, great detector!!

Super nice. I agree with Steven that the slight decrease in resolution for a stand alone detector is worth it not to have the internal activity. Green with envy... :)

Too bad it is far out of reach to DIY a CeBr3 crystal from scratch. I'd really like to have one. Can't afford it though.

Great probe Steve!
What’s the price of this crystal?
