Overview

This family of High Voltage power supplies includes boards housing up to 48 output channels. The boards are designed to provide voltage up to 1.5 kV, and current up to 10 mA.

All the boards are compatible with all CAEN Universal Multichannel Power Supply Systems. The available grounding option, depending on the family are the following: Common Ground (AGxxxx) or Common Floating Return (Axxxx), excluding the A1515 family which is Fully Floating up to 5 kV as detailed below. Common Floating Return allows on-detector grounding reducing the noise level; the floating return is insulated from the crate earth up to ±50 V (with a 65 V hardware limit). All the boards are provided with both current and voltage protections. If overcurrent occurs, the corresponding channel can be programmed either to turn of after a programmable trip time or to keep on providing the maximum allowed current. This particular feature allows the module to perform as a current generator. The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 100 V/s range (1 V/s step) for the A1515 family and in the 1 ÷ 500 V/s range (1 V/s step) for the A1538 and A7038 family.

The family is composed by:

  • A1538D / AG538D
  • A1515 boards
  • A7038

A1538D / AG538D

A1538D is a single width (5TE wide) board housing 12 independent high voltage and high-power channels. The output voltage range is 0 ÷ 1.5 kV, with 10 mA maximum output current (12W channel max output power) and 50 mV set and monitor resolution. The board is available with either positive or negative output polarity and equipped with SHV coaxial connector.

A1515 boards

A1515x boards house 14 or 16 independent, fully floating High Voltage channels and five special versions are perfectly suited for GEM detectors. All versions are equipped with Radiall Multipin connectors. The channels have floating return, independent one from another, insulated up to 5 kV. The output voltage range is 0 ÷ 1/1.3/1.4 kV, with 20 mV set and monitor resolution. Maximum output current is 1/3 mA.

Five special version of the board (A1515TG/QG/CG/TGHP/V) have been designed specifically for Gas Electron Multiplier (GEM) detectors (Triple, Triple designed for high rate, Quadruple, Cylindrical GEM detectors and Vertex detectors). These boards have the channels internally stacked in order to power up 2 independent Triple GEM / Quadruple GEM / Triple Cylindrical GEM chambers. This configuration permits to avoid any possible issue related to the detector discharge and avalanche effects and gives the possibility to fine tune the voltage on each detector layer easily.

A7038

A7038 is a 32 or 48 independent high voltage channels board available in different versions equipped with SHV or with DB37 connectors.
The output voltage range is 0 ÷ 1 kV (20 mV set and 2 mV monitor resolution), with 100 µA maximum output current (2 nA set and 500 pA monitor resolution).

Universal Multichannel System - Mainframes

Modularity, Compatibility, Connectivity, Usability and Solidity are the keywords of the system design. The Mainframes have been specifically designed to power all detector technologies found in modern Physics Experiments, such as photomultipliers, wire chambers, streamers tubes, silicon detectors and others.

The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.

Software

A complete set of Software Tools is available (free download) to control CAEN Universal Multichannel Power Supply Systems, from low level libraries to graphical application software:

CAEN, in collaboration with CERN, has developed an OPC server which allows control of its power supply systems by any OPC compliant client application.
HiVoCS HiVoCS is a Web Interface available on any SY4527-SY5527 CPU. This Interface can be accessed directly via browser without installing any additional software.
EPICS IOC Mainframes CPUs integrates an EPICS Input / Output Controller (IOC) that provides access to the Process Variables using the Channel Access Protocol.
CAEN HV Wrapper Library It is a set of ANSI C functions bundled in a library, providing the software developer an unified software interface for the control of all the CAEN Power Supply products
GECO2020 CAEN General Control SW for High Voltage Boards and Systems. it can manage and control CAEN HV power supplies in any form factor as if they were an unique device.
