Research and development for the International Linear Collider

1) Time Projection Chamber (TPC) R&D for the International Linear Collider

Standard Model (SM) is at present the most comprehensive theory of subatomic particles and their interactions. Discovery of what looks to be the Higgs boson at the Large Hadron Collider (LHC) opens new horizons in particle physics. In fact there is a clear consensus in the world particle physics community that a new next generation high-energy electron-positron collider will be needed to fully understand the new physics discovered by the LHC. The 500 GeV International Linear Collider (ILC) is presently at an advanced planning stage.  Carleton physicists are members of the International Large Detector (ILD), one of the two detector concepts approved to proceed with preparing a detailed Technical Design Report. A large volume Time Projection Chamber (TPC) is the proposed main charged particle tracking detector for ILD. The Carleton group has been among the leading groups in ILD-TPC R&D from the very beginning and its contributions have been internationally recognized. A new MPGD readout concept of charge dispersion, developed at Carleton, has achieved an unprecedented world-record resolution of 50 microns in prototype tests. The charge dispersion MPGD TPC readout concept was adapted by the ILD-TPC group with further development of the technology being done jointly by Carleton and a group from France. The ideal candidate for this summer job will have a mix of skills in experimental physics and software. Our students in the past have helped us in testing our TPC's with cosmic rays and with particle beams in Europe and in Japan. Our previous COOP and summer students have also written most of our simulation software. Some of the students making outstanding contributions became co-authors in our published papers. Two of our students subsequently spent their COOP year working with our colleagues in France. Students joining our group will help in developing, and modifying our simulation and analysis software and incorporating our existing software into Mokka and Marlin LCIO standards adapted by the collaboration. The students will also be expected to contribute to the hardware and software efforts for beam tests of the ILD 1-meter Large Prototype TPC at DESY laboratory in Germany for which some travel may be required. 

 
2)  Micro pattern gaseous detectors (MPGD)

Micro pattern gaseous detectors (MPGD) were designed to give excellent response for very high particle flux experiments. The versatility of MPGD leads the way for many different applications in various fields of research. The RD51 collaboration at CERN aims to push forward technological and system aspects of MPGD. Current trends in MPDG technology include new fabrication processes that lead to improvement in performance for detectors of various sizes and shapes. Basic experimental studies and evaluation for high energy physics, particle astrophysics, nuclear physics, industrial and medical imaging, as well as development of radiation hard technology and fast electronics can be studied with the Monte Carlo technique. This summer project will focus on the implementation of the simulation of MPGD into the C++ GEANT4 framework.
