A Study of Bare X‐ray Diode Saturation Due to a High Fluence X‐ray Pulse

We have studied the response of bare, aluminum photocathode, x‐ray diodes (XRD’s) exposed to a soure of pulsed x‐rays from a laser produced plasma. Three cross calibrated detectors were placed at varied distances from the source. Saturation occurred at the Child‐Langmuir predicted value. When low transparency screens were used as attenuators for the XRD’s, saturation occurred at values below those predicted by the Child‐Langmuir formula.
