Optical Readout Time Projection Chamber (O-TPC) for a Study of Oxygen Formation In Stellar Helium Burning
We are developing an Optical Readout Time Projection Chamber (O-TPC) detector for the study of the 1̧2ag reaction that determines the ratio of carbon to oxygen in helium burning. This ratio is crucial for understanding the final fate of a progenitor star and the nucleosynthesis of elements prior to a Type II supernova; an oxygen rich star is predicted to collapse to a black hole, and a carbon ri...
متن کاملHelium burning: Carbon and oxygen formation studied with an optical readout TPC (O-TPC) Moshe Gai and the Uconn-Yale-Duke-Weizmann-Ptb-Ucl collaboration Electromagnetic transitions as a probe of clustering in nuclei
We have measured the C(γ, 3α) reaction with an Optical Time Projection Chamber (O-TPC) detector operating with the CO2(80%) + N2(20%) gas mixture and gammaray beams from the HIγS facility of the TUNL at Duke. We measured complete angular distributions (between 9.1 10.7 MeV) from which we determine the cross section yield curve and E1-E2 relative phases leading to an unambiguous identification o...
متن کاملPerformance of the TPC with Micro Pixel Chamber Readout: micro-TPC
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 1...
متن کاملA TPC with Triple-GEM Gas Amplification and TimePix Readout
We present measurements with a GEM based TPC prototypes and the TimePix CMOS ASIC as charge collecting anode. Tests with a small prototype were performed in a 5GeV electron beam at DESY. It is shown that the point resolution for short drift distances is better than 20 μm. The achieved time resolution is better than 10 ns at 100MHz clock frequency. Furthermore, experimental studies with an enlar...
متن کاملTPC Performance in Magnetic Fields with GEM and Pad Readout
A novel charged particle tracking device, a high precision time projection chamber with gas electron multiplier and pad readout, is a leading candidate as the central tracker for an experiment at the International Linear Collider. To characterize the performance of such a system, a small TPC has been operated within a magnetic field, measuring cosmic-ray and laser tracks. Good tracking resoluti...
