Previous What's New at NEC

Welcome to the NEC Web Site

March 1999 - May 1999

1999 continues to be a very busy year for NEC with a wide variety of projects. Pelletron systems used for space simulation, anti proton cooling, routine materials analysis and components for AMS are all presently in manufacture.

Electron Cooling - The group at Fermilab has purchased a Pelletron Model 5URE-2 for use on the new anti-proton injector accumulator ring. The Model 5URE-2 is a vertical, single-ended 5 MV Pelletron with parallel acceleration tubes. One set of acceleration tubes is for electron acceleration and the second set of acceleration tubes is for electron deceleration to the terminal. Please note our previous entry in "What's New at NEC" describing the performance of the test conducted at NEC. It is expected that very large currents, 100's of milliamps, approaching 1 amp of DC electrons will be traveling through the anti-proton beam path. Shipment is expected in April, 2000.

134 MC-SNICS - The 134 Sample Multi-Cathode SNICS source has been delivered to the Woods Hole Oceanographic Institute installed and accepted on-site. This is the second source of this type to be in use for high throughput AMS. After careful pre-installation set up by Dr. Karl von Reden and his crew, it was less than 24 hours from the beginning of initial alignment, source assembly, cabling, and achieving vacuum that the first 14C counts were detected using this source.

Development on the 40 MC-SNICS and the 134 MC-SNICS continues at NEC. Both of these sources are now available for use with gas samples.

1.7 MV Tandem Pelletron - In March, NEC received an order for a Pelletron Model 5SDH from the Electronics Materials Engineering Department of the Research School of Physical Sciences and Engineering at the Australian National University in Canberra, Australia. The 5SDH Pelletron will be used primarily for routine materials analysis, RBS, ERD, etc. It will be housed in the same facility as the high current Pelletron Model 5SDH-4 and the 14 MV tandem Pelletron Model 14UD. Shipment is scheduled for February, 2000.

4 MV Single-Ended Pelletron - The Japan Atomic Energy Research Institute in Tokai, Japan ordered a Pelletron Model 4UH-HC with nanosecond bunching and pulsing. The single-ended Pelletron will be used as a standard for the calibration of radiation detection equipment. It can be used both in nanosecond pulsed beam mode and DC. The Pelletron system is expected to be shipped in early February, 2000.

Conferences - NEC will be participating in the Joint International Conference on Ion Beam Analysis and the European Conference on Accelerators in Applied Research and Technology (IBA-14/ECAART-6). This conference is being held in Dresden, Germany from July 26 to July 30, 1999.

NEC will also have exhibits at the 8th International Conference on Accelerator Mass Spectrometry, September 6-10 to be held in Vienna, Austria (AMS-8) , at SNEAP 1999 to be held in Knoxville, Tennessee, October 25-28, and the Fall Meeting of the Material Research Society (MRS) to be held in Boston, Massachusetts, November 30 through December 2, 1999.
