The AXR/PA-210 or AXR/PA-230 alone, is for experts/OEMs in the field. Any Amptek detector can be used (Si-PIN, SDD, or CdTe). There are many options for this configuration as can be seen in the pictures below. The customer either needs to provide custom heat-sinking and a custom enclosure for the AXR/PA-210 or AXR/PA-230, or order the housings shown below. Additionally, the customer needs to provide several external power supplies, a shaping amplifier and MCA, or digital processor, and communication with the host computer.
|Pin 1||Cooler Return||Best to connect to ground at cooler power supply|
|Pin 2||Cooler Supply||Current = 350 mA maximum, voltage = 3.6 V maximum with <100 mV peak-to-peak noise|
|Pin 3||Preamp +5 V DC||+5 V DC, 15 mA with no more than 50 mV peak-to-peak noise|
|Pin 4||Preamp -5 V DC||-5 V DC, 15 mA with no more than 50 mV peak-to-peak noise|
|Pin 5||Ground (signal return)||Connect to signal return (processor/shaping amplifier ground)|
|Pin 6||Signal Out||Connect to input of shaping amplifier or digital processor|
|Pin 7||Temp||Temperature diode, see Temperature Diode Calibration Curve below|
|Pin 8||Ground||Chassis Ground|
|Pin 10||High Voltage (HV)||Si-PIN (positive HV): +100 to +200 V @ 1 µA (varies for different detector types) very stable <0.1% variation
SDD (negative HV): -85 to -200 V @ 25 µA (varies for different detector types) very stable <0.1% variation
Pin 3 to Pin 7 resistor (R19) is to supply current to the temperature diode.
