Overview
The CAEN Mod. A1560H is specifically designed for Germanium detector. It is a single width board (5 TE wide) that houses 8 or 16 independent high voltage channels equipped with individual hardware enable and with SHV or Radiall Multipin connector.

Radiall multipin connector
Single width (5 TE wide), 16 channel for Mod. A1560HNE, A1560HPE |
|
SHV connector
Single width (5 TE wide), 8 channels for Mod. A1560HDNE, A1560HDPE |
Consult our connectors reference page for technical information.
The HV channels share a common floating return, which allows on-detector grounding reducing the noise level; the floating return is insulated from the crate earth up to ±50 V (with 65 V hardware limit). The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 500 V/s range (1 V/s step).
The board is available with either positive, negative or mixed output polarity. The Mixed version comes with 4 positive and 4 negative channels (only with SHV connectors).
The output voltage range is 0 ÷ 6 kV, with 10 mV monitor resolution. The maximum output current is 20 µA, with 50 pA monitor resolution.
Independently programmable for each channel:
| Output voltage | 0 ÷ 6 kV | step: 100 mV |
| Current limit | 0 ÷ 20 μA | step: 500 pA |
| V Ramp up/down | 1 ÷ 500 V/sec | step: 1 V/sec |
| TRIP parameter | 0 ÷ 999.9 s; 1000 s = Infinite | step: 0.1 s |
Safety features allows the module to perform as a current generator and includes:
| Channels | can be enabled or disabled through the Global Interlock logic. |
| Remote Enable/Disable | front panel independent contacts available for all channels. |
| Overvoltage and Undervoltage warning | when the output voltage differs from the programmed value. |
| Overcurrent detection | when a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
| Hardware VMAX | maximum output voltage can be set via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software. |
| Safety Board Interlock | this protection disables the HV generation when the HV outputs are not connected to their loads (only for Multipin Connector versions). |
For boards with Radiall 52 pin connector are available the following accessories:
