Single Pulse Emittance Measurement Technique for Intense Relativistic Electron Beams

Diamond detector in absorbed dose measurements in high‐energy linear accelerator photon and electron beams

Diamond detectors (DD) are preferred in small field dosimetry of radiation beams because of small dose profile penumbras, better spatial resolution, and tissue-equivalent properties. We investigated a commercially available 'microdiamond' detector in realizing absorbed dose from first principles. A microdiamond detector, type TM 60019 with tandem electrometer is used to measure absorbed doses i...

Absorbed Dose Determination in Photon and Electron Beams

The IAEA Code of Practice for Absorbed Dose Determination in Photon and Electron Beams TRS 277 gives recommendations for the absorbed dose determination in high energy photon and electron beams based on the use of ionization chambers calibrated in terms of air kerma. It was the task of the present work to test the validity of the Code for *°Co gamma radiation for ton different types of ionizati...

Measurement of Subpicosecond Electron Pulse Length*

A new frequency-resolved bunch-length measuring system has been developed at the Stanford SUNSHINE facility to characterize subpicosecond electron pulses. Using a far-infrared Michelson interferometer, this method measures the spectrum of coherent transition radiation emitted from electron bunches through optical autocorrelation. The electron bunch length is obtained from the measurement with a...

Relative timing characteristics of the one pulse per second (1PPS) output pulse of three GPS receivers

The atomic clocks orbiting around the earth in GPS satellites can be utilised by anyone to obtain accurate timing. All that is required is an inexpensive GPS receiver and a clear view of the sky. This has enabled a revolution in applications requiring synchronization such as cellular networks, telecommunications timing, digital TV and radio transmission, calibration laboratory systems and the i...
