In addition to the Proton Irradiation Facility the Paul Scherrer Institute (PSI) also operates two Electron exposure Facilities: Low Energy Electron Monochromator LEEMON and High Energy Electron Site (HEES) for testing of components and electronic parts that require electron beams. Both facilities are designed in a user friendly manner being commonly available for experiments. Electron facilities allow mainly to investigate:

· Space radiation environment by on-earth simulations

· Properties of radiation monitors for space and laboratory applications

· Radiation hardness and Single Event Effects in electronics

· Basic mechanics of radiation effects in semiconductors

Leading features

Both electron facilities allow conducting studies on instrument response, shielding optimizations and radiation induced effects. They not only enables experiments with realistic space electron environment but also provides mono-energetic beams. A wide range of applications is feasible due to elementary design aspects assuring:

1. Broad range of energies and intensities of the electron beam

2. Experiment adaptable monitoring of flux and dose

3. Fast and uncomplicated experimental setup

4. Transparent operating procedure

5. User friendly data acquisition system

6. Flexibility towards customers needs

Operation and irradiation experiments

As a prime user the low energy facility LEEMON is available for irradiation experiments in the laboratory test area on weekly basis relying on high intensity radioactive sources. The tests with high energy electrons at HEES are performed using secondary beams from the main PSI accelerator in a dedicated piM1 test area. All HEES irradiations are performed within beam blocks allocated for experiments during Accelerator Users Meeting. Short-duration experiments require an irradiation request and order. Project extended over longer period or with substantial demand for the beam time need an approval by the Research Committee and PSI Technology Transfer Office. The PSI beam production schedule for the next period can be found at Accelerator Physics and Development Division beam production page. The schedule for the next week is also available.
