Electron Source Power Supply ES40-PS

Description

The power supply allows fine adjustment of beam energy, density, position on the sample and also beam profile. Advanced scanning features allow for independently controlled scanning range and scanning speed. All settings can be stored and recalled automatically after unit switch on, or else manually adjusted. The unit also features a built in timer and automatic standby mode.
The ES40-PS can be supplied as a full width 19″ rack mounting unit (3U height) or free standing. Easy firmware update via USB port. Unit can be remotely controlled via RS232/485 or Ethernet interfaces.

Application

The ES40-PS power supply is intended to use with the ES40C1 Low Energy Electron Source or Double Pass Mini Cylindrical Mirror Analyzer CMA 40CF. The power supply allows fine adjustment of the electron beam profile to achieve a small spot at high energy and emission currents.

Options

- Software control (Version Pro, Extended or Library Module),
- Analog I/O card for vacuum measurement (1 gauge).
