The LeCroy Model HV4032 is the first complete photomultiplier high voltage system.
Remote operation affords both operational and economic ad- vantages.
By mounting the high voltage chassis near the appa- ratus, long cable runs are eliminated along with the expense and manpower required to install them. Having computer con- trol finally closes the loop, allowing the continuous gain control required of large systems. The HV4032 replaces the conventional high voltage supply, the space-consuming distribution system, the monitor ADC system, and often several kilometers of high voltage cable. It also allows ease of setup under local control, remote operation without a computer, and on-line computer control. It has suffi- cient local intelligence to guard against a possible catastrophe caused by power failures, computer errors, software bugs, or even operator errors.
