Subnanosecond Chopper-Buncher for a 14UD pelletron
2014 A novel chopper-buncher system is under construction for the Rehovot 14UD Pelletron. Beam dynamics calculations of that system are described. The ultimate performance for nickel ions is 100 picoseconds pulse, at a repetition rate of 4 MHz, and transmission of 15 % of the d.c. beam current.

متن کاملField portable XRF analysis of environmental samples.
One of the critical factors for successfully conducting contamination characterization, removal, and remedial operations at hazardous waste sites is rapid and appropriate response to analyze samples in a timely fashion. Turnaround time associated with off-site analysis is often too slow to support efficient utilization of the data. Field portable X-ray fluorescence (FPXRF) techniques provide vi...
متن کاملApparatus for low temperature thermal desorption spectroscopy of portable samples.
An experimental setup for low temperature thermal desorption spectroscopy (TDS) integrated in an ultrahigh vacuum-chamber housing a high-end scanning probe microscope for comprehensive multi-tool surface science analysis is described. This setup enables the characterization with TDS at low temperatures (T > 22 K) of portable sample designs, as is the case for scanning probe optimized setups or ...
متن کاملQuantitative phase microscopy of biological samples using a portable interferometer.
This Letter presents the τ interferometer, a portable and inexpensive device for obtaining spatial interferograms of microscopic biological samples without the strict stability and the highly coherent illumination that are usually required for interferometric microscopy setups. The device is built using off-the-shelf optical elements and can easily operate with low-coherence illumination, while...
متن کاملCold Chopper System for Mid-infrared Instruments
We have developed a cold chopper system for mid-infrared observations. This system is installed into the newly developing mid-infrared instrument, MAX38, for the University of Tokyo Atacama 1.0-m telescope. It is cooled to about 9K. The cold chopper mirror is controlled by a piezoelectric actuator with a flexure hinge lever, and enables square-wave chopping at a frequency up to 7.8 Hz. At the m...
