The new Surrey ion beam analysis facility
نویسندگان
چکیده
We present the characteristics of an ion beam analysis facility based on a fully computer controlled 2 MV Tandetron commissioned in 2002. The terminal voltage temperature stability is measured using the 3036 keV O(a; a)O resonance. A microbeam beamline with an Oxford triplet lens and a coolable sample holder has been built. We report new temperature dependent time-resolved IBIC measurements from CZT detectors that illustrate the capability of the system. A millibeam beamline has been built with a 6-axis goniometer capable of handling 100 mm wafers through an airlock with a z-axis for the precise location of the sample surface at the eucentric point. This instrument is designed for routine RBS/ERD and channelling applications, and incorporates a versatile controller capable of fully automated data collection. 2004 Elsevier B.V.

متن کامل"Broadbeam" irradiation of mammalian cells using a vertical microbeam facility.
A "broadbeam" facility is demonstrated for the vertical microbeam at Surrey's Ion Beam Centre, validating the new technique used by Barazzuol et al. (Radiat Res 177:651-662, 2012). Here, droplets with a diameter of about 4 mm of 15,000 mammalian cells in suspension were pipetted onto defined locations on a 42-mm-diameter cell dish with each droplet individually irradiated in "broadbeam" mode wi...
متن کاملBeam Monitors of Nirs Fast Scanning System for Particle Therapy
At National Institute of Radiological Sciences (NIRS), more than 6500 patients have been successfully treated by carbon-ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with three-dimensional pencil beam scanning irradiation system. The commissioning of NIRS fast scanning system installed into the new facility was started in S...
متن کاملPatient handling system for carbon ion beam scanning therapy
Our institution established a new treatment facility for carbon ion beam scanning therapy in 2010. The major advantages of scanning beam treatment compared to the passive beam treatment are the following: high dose conformation with less excessive dose to the normal tissues, no bolus compensator and patient collimator/multi-leaf collimator, better dose efficiency by reducing the number of scatt...
