Performance of the TPC with Micro Pixel Chamber Readout: micro-TPC

چکیده
Micro-TPC, a time projection chamber (TPC) with micro pixel chamber (μ-PIC) readout was developed for the detection of the three-dimensional fine (∼ sub-millimeter) tracks of charged particles. We developed a two-dimensional position sensitive gaseous detector, or the μ-PIC, with the detection area of 10 × 10 cm and 65536 anode electrodes of 400 μm pitch. We achieved the gas gain of more than 10 without any other multipliers. With the pipe-line readout system specially developed for the μ-PIC, we detected X-rays at the maximum rate of 7.7 MHz. We developed a micro-TPC with the μ-PIC and threedimensional tracks of electrons were detected with the microTPC. We also developed a prototype of the MeV gamma-ray imaging detector which is a hybrid of the micro-TPC and NaI (Tl) scintillator so that we showed that this is a promising method for the MeV gamma-ray imaging.

Realization of a micro-TPC, a time projection chamber(TPC) which can detect three-dimensional fine tracks of charged particles, has been desired for years. We developed the μ-PIC, a twodimensional fine position detector, and a fast readout electronics in order to develop such an “electric cloud chamber”. In this paper, detector description and performance of our micro-TPC and one of its applica...

A micro time-projection-chamber (micro-TPC) with a detection volume of 23×28×31 cm was developed, and its fundamental performance was examined. The micro-TPC consists of a micro pixel chamber with a detection area of 31×31 cm as a two-dimensional imaging device and a gas electron multiplier with an effective area of 23×28 cm as a pre-gas-multiplier. The micro-TPC was operated at a gas gain of 5...
متن کاملPerformance of a micro-TPC for a time-resolved neutron PSD
We report on the performance of a micro-TPC with a micro pixel chamber(μPIC) readout for a time-resolved neutron position-sensitive detector(PSD). Threedimensional tracks and the Bragg curves of protons with energies of around 1 MeV were clearly detected by the micro-TPC. More than 95% of gamma-rays of 511 keV were found to be discriminated by simple analysis. Simulation studies showed that the...

A large volume Time Projection Chamber (TPC) is being considered for the central charged particle tracker for the detector for the proposed International Linear Col-lider (ILC). To meet the ILC-TPC spatial resolution challenge of ∼ 100 µm with a manageable number of readout pads and channels of electronics, Micro Pattern Gas Detectors (MPGD) are being developed which could use pads comparable i...
متن کاملMeV Gamma-Ray Imaging Detector with micro-TPC
We propose a new imaging gamma-ray detector in the MeV region. By measuring the directions and energies of not only a scattered gamma ray but also a recoil electron, the direction of an incident gamma ray would be essentially reconstructed event by event. Furthermore, one of two measured (zenith and azimuth) angles of a recoil electron gives us an additional redundancy which enables us to rejec...
