BNL test electron beam ion source operation on a 100 kV platform (abstract)
Abstract
At BNL, we are preparing to build an electron beam ion source (EBIS) that will satisfy the requirements of the relativistic heavy ion collider (RHIC), e.g., Au{sup 32+} ions of about 3x10{sup 9} particles/pulse in 10-40 {mu}s pulses at 5 Hz. In addition, the EBIS is required to deliver beams such as He{sup 2+}, C{sup 6+}, O{sup 8+}, Si{sup 14+}, Ti{sup 18+}, Fe{sup 21+}, and Cu{sup 22+} in {approx}2-3 mA, 10 {mu}s pulses at 5 Hz to meet the demands of the NASA Space Radiation Laboratory (NSRL) experimental program. Development studies continue to be carried out on the BNL test EBIS, a half-length full electron beam power prototype of the RHIC EBIS which is in the construction phase. In preparation for acceleration of EBIS ions by a radio frequency quadrupole, we have upgraded the test EBIS for operation on a nominal 100 kV pulsed platform to allow seed ion injection at 10-20 kV and ion extraction up to 100 q kV. The installation includes a pulsed high voltage power supply, a 200 kV A 100 kV isolation transformer, and a capacitive electron collector supply and electron gun bias supply which allows operation in a similar mode to the RHIC EBISmore »

Initial testing has been made using ion beams of He{sup 2+} and Ar{sup 10+} formed from gas injection and ions have been extracted with energies up to 88 q keV. Total ion current measurement has been made and charge state distributions have been obtained using a Mamyrin time of flight. Results of emittance measurements and profile distributions, obtained at various energies using both pepperpot and slit-foil emittance meters, will be presented.},
