Abstract

The Linac Coherent Light Source (LCLS) produces brilliant x-ray in femtosecond pulses of high intensity. Many of the experiments performed at the LCLS use expensive pixel area detectors - the majority of which incorporate custom integrated circuit chips (ASIC). Such circuit chips are susceptible to radiation damage. To protect against this, micro-patterned tungsten foils were designed to cover the section of the circuit chip that extends beyond the sensor near the wire-bond pads. A description of the problem along with the details of how the tungsten foils were fabricated and installed will be given.
