Does anybody know where I can buy a CsI(TI) scintillation crystal to a good (cheap) price? I currently use CsJ(TI) but this crystal has an FWHM of about 12%. The CsI(TI) is typically in the range of 6-7%.
I have of course checked sites like eBay etc. but have not been able to find an offer that fits the budget. Any advice, tips etc. are appreciated.
