Registration and Arrival

Before arriving to PSI, please register as a user at You will find all necessary information in there. You will also be able to complete the safety course as well as apply for your personal dosimeter and the entry card. Both are required during your stay at PSI.

Experimental Procedure

Please provide us enough information for optimal planning of the whole test. Data such as size of your active component area, number of samples under test at the same time is very important for preparation of the proton beam, collimators and shielding. This with the total number of components to be tested, required energies and doses allows to prepare the most optimal test procedure and minimize the required beam time.

Sample Mounting

Please consider making use of the standard sample holder. It allows for fast and easy mounting of your device (board, plate, chip etc.) on the beam and setting its position. Don't hesitate to contact us if you need any assistance.

Cable Connections

The length of cables between test area and control barrack equals to ca. 30 m. User can either bring its own cables or use some of existing cables for their connections. Typically we provide some BNC and HV cables as well as RS232 D25 and RJ49 twisted pair connections. There is also a possibility to remotely control user's PC located in the test site from the control barrack using Monitor/Mouse/Keyboard extender or another PC with suitable software installed (PCanywhere or VNC).

Net Voltages and Sockets/Plugs

Nominal parameters are 220 V, 50 Hz with Swiss type of plugs and sockets. Please inform us in advance if we should provide interfaces between Swiss and other 'European' types of sockets. It will also be helpful to bring socket- boards with yourself in order to plug your devices.

Device Activation

It is natural that all materials exposed to protons will be activated and for certain time cannot be taken out of the radiation controlled area. You can help to shorten the storing and activity decay period you by optimizing your test setup: •minimize the irradiated area of the device under test e.g. use masks and collimators that can be de-attached from rest. •expose to protons as little of the material bulk as possible e.g. leave the space behind the tested device empty. •Use low Z materials whenever possible e.g. take plexiglas instead of Aluminum

Radiation Control After Test

Proton exposed devices must be controlled by PSI Health Physicists after completion of the test. Without it, no items are allowed to be removed outside the radiation zone. Health Physicists are available during normal working hours from Monday to Friday (8:00 to 17:00).

Shipment and Customs
