CsI(Tl)mini detector

 sample Data


Size of crystal: 10mm×10mm×10mm
Size of product : 12cm×6cm×2cm
Interface : D-Sub 9Pin
        Case GND(1)、+5V(3)、GND(5)、−5V(8)
HV:+36 (N battery×3)Built in Replacement Cycle:2Year
Conecter:LEMO 30cmLEMO->BNC Cable is included


iFKR-ZIP Pro is most supreme measurment instrument of our product.
twin 2x2x1inch Crystals have placed to both side of detective sample.
Which constituition makes High detective efficiency and less amount of sample request.
if we Compare to conventional measuring instrument like Marineli, 1liter to 100g.

we have confidence to our other product as well, but measuring with 1 deteceter always have problem of
sum-peak. so only this product ignor sum-peak problem.
containing 2 detectors, which means iFKR-ZIP PRO is able to measur the sample in more than 2 mode.
ANTI COINC mode, COINC mode, and Normal mode.

we, SMTX has Convicted CsI detector has Developed enough and now so close to Ge detecet with
releasing this product!

ADC2318 is ADC module for MCA.Constituited by Exclusive use of nuclear detective peak detect circuit and ADC.
this product have Crucial spec requested to MCA, such as "unmatched accuracy for peak detection" and
"fine differencial nonlinerity". those specs are confirmed by pulser at 1 channel.(pulse 1ch.jpg)。

tempreture stability is customed by 100ppm to 10ppm.
requested power has been developed to more ecological as 50mA to 18mA.and half sized.

test report and inspection report is able to order optionaly.
