Abstract

The TRIUMF Fast Ion Counter (TRIFIC) is a tilted-grid gas counter detector for identifying the impurities in radioactive ion beams (RIBs). Placed at zero degrees downstream of a primary reaction target at the TRIUMF ISAC-II facility, TRIFIC provides accurate Z identification of beam species on an event-by-event basis at a rate of up to 5 × 10⁵ particles per second and functions as a beam composition monitor at rates up to 5 × 10⁷ particles per second. With this additional level of diagnostics, RIB experiments at TRIUMF are able to reach levels of sensitivity not previously possible. Details pertaining to the construction and instrumentation of TRIFIC as well as results from the commissioning of the detector are introduced.

Journal Article Bricault, Pierre ; Ames, Friedhelm ; Achtzehn, Tobias ; ... - Review of Scientific Instruments

The ISAC facility at TRIUMF utilizes up to 100 {mu}A from the 500 MeV H{sup -} cyclotron to produce the radioactive ion beam (RIB) using the isotopic separation on line method. The ISAC-I facility comprised the RIB production target stations, the mass separator, and the beam delivery to low energy area and to a room temperature linear accelerator composed of a four-rod radio frequency quadrupole and an interdigital H-type structure drift tube LINAC. ISAC-I linear accelerator can provide beam from A=3 to 30 amu with an energy range from 0.15 to 1.5 A MeV. Since the beginning of operations targetmore »« less

Status report of the radioactive ion beam production at TRIUMF (invited)

Journal Article Bricault, Pierre - Review of Scientific Instruments

The ISAC radioactive ion beam (RIB) facility has been operational since November 1998. The ISAC Facility at TRIUMF utilizes up to 100 {mu}A proton intensity at 500 MeV from the existing H{sup -} cyclotron to produce RIB using the isotopic separation on-line (ISOL) method. The science programs at ISAC range from nuclear astrophysics to fundamental symmetry. The facility can deliver RIB to the low energy area and a linear accelerator composed of a four-rod radio frequency quadrupole and a linear accelerator can provide beam from A=3 to 30 amu with an energy range from 0.15 to 1.5 A MeV.

Nuclear Structure of Radioactive Neutron-Rich Nuclei with 4pi Detector Arrays

Conference Wu, C Y ; Becker, J A ; Cline, D

In-beam studies of {gamma}-ray spectroscopy of radioactive neutron-rich nuclei using the 4{pi} TIGRESS array at TRIUMF requires a ''tag'' to improve the selectivity of the detected {gamma} rays in the high {gamma}-ray background produced by radioactive beams and the need for Doppler-shift correction. We propose development of two types of large solid angle auxiliary charged particle detectors to be used in conjunction with TRIGRESS in order to provide the required tag. The initial phase of detector development will focus on research involving light-mass radioactive beams with Z {le} 20. Gas avalanche detectors, such as CHICO, are not the ideal detectormore »« less

Progress update on cryogenic system for ARIEL E-linac at TRIUMF

Journal Article Koveshnikov, A. ; Bylinskii, I. ; Hodgson, G. ; ... - AIP Conference Proceedings

TRIUMF is involved in a major upgrade. The Advanced Rare IsotopeE Laboratory (ARIEL) has become a fully funded project in July 2010. A 10 mA 50 MeV SRF electron linac (e-linac) operating CW at 1.3 GHz is the key component of this initiative. This machine will serve as a second independent photo-fission driver for Rare Isotope Beams (RIB) production at TRIUMF's Isotope Separator and Accelerator (ISAC) facility. The cryogens delivery system requirements are driven by the electron accelerator cryomodule design [1, 2]. Since commencement of the project in 2010 the cryogenic system of e-linac has moved from the conceptual designmore »« less

Journal Article Schmor, P W - AIP Conference Proceedings

Construction has begun on ISAC, a radioactive ion beam (RIB) and accelerator facility that utilizes the ISOL (on-line isotope separation) production method. A five-year budget for this new radioactive beam facility at TRIUMF was approved in June 1995. ISAC includes: a new building with 5000 m{sup 2} of floor space, a beam line with adequate shielding to transport up to 100 {mu}A of 500 MeV protons from the TRIUMF cyclotron to two target/ion-source stations, remote handling facilities for the targets, a high-resolution mass-separator, linear accelerators and experimental facilities. The ISAC target/ion source station permits the production of nuclei far frommore »« less
