5V and USB cable to your laptop. Amptek inside. Runs on DPPMCA program.

Looking good
Like the X-123 Amptek
Much cheaper ?with Geo trademark?
Will be anxiously waiting for more display pics

Yes it is a universal one. It is important to use this one power supply, it can provide 2 amps, and that capacity is needed during initial turn-on phase of the cooler.

Geo Good on universal plug power settings One usually overlook the amperage rating. A right voltage??with wrong amperage can be a disaster. Taray

Charles what are you running Si-PIN HV and gain?

12 hours or so into the long term aging test. No noticeable change in calibration at 5.9 keV, temperature stable etc. Heatsink warm to the touch like a puppy.
15 seconds and the peak search function of software identifies the Fe-55 peak with no problem. This is WITH? NO SHIELDING whatsoever on the sensor.
FYI- I? routinely run tests from 24 hours to weeks long for a single test, with no downtime.
UsingAmptek? DPPMCA free software for control and display.

that's then latest aluminum version, the brass was great but had bothersome self-excited copper/zinc line.
It's just a mtter of time.
Coffee break over, back to the shop now....

Geo,
Is there a reason you¡¯re running the HV at 130v. Most Si Pins
should run around 150 to 200. Was 130 the optimal set point for that detector? ?A
low voltage will increase the capacitance and increase the electronic noise. Note
?the peaking time is set at 4.8 usec which is ok for a high count rate but you¡¯re
losing resolution and more importantly increasing the electronic noise. Try setting
that around 25 -32 usec for a low count rate Am source or a count rate below 10Kcps
and use a shaping time around 11 -14 usec. ?

"?Was 130 the optimal set point for that detector?"
You are right, the one I normally running my Home Lab? is set to 190V. This is a brand new one for a friend,? it is the minimum HV where this particular Si-PIN came alive. First test has run 24 hours, everything stable, using original calibration. Time to build the next one now. Further testing is scheduled.
24Hr stability test .png and .mca? attached.
Tomorrow a different new one.

#2 in this series, or as the song says "Second verse, same as the first".
Geo

The second one is serial 1`9012, was set up from the factory so left it alone.
Looks fine.

Any internal collimators?
Will help cut down small peak.
