Measurement of the Longitudinal Polarization of the HERA Electron Beam Using Crystals and the ZEUS Luminosity Monitor
نویسنده
چکیده
A measurement of the longitudinal polarization of the electron beam at HERA utilizing coherent interactions of high energy photons in crystals is described. Modification of existing facilities would allow an independent polarization measurement and a verification of birefringence phenomena in crystals for 20–30 GeV photons. Relevant experimental issues and systematic uncertainties are also presented.

متن کاملA Luminosity Spectrometer for the Zeus Experiment at Hera
The HERA luminosity upgrade is expected to generate two major problems in the current method of luminosity determination which is based on counting brehmsstrahlung photons: damage of the calorimeter monitor due to high primary synchrotron radiation and large multiple event (pile-up) corrections. The luminosity spectrometer presented in this talk, is a novel method that reduces the impact of the...

متن کاملElectron polarization measurement using a Fabry-Pérot cavity at HERA
A new Compton longitudinal polarimeter currently under construction for HERA is presented. The key component of the polarimeter is a Fabry-Pérot cavity located around the electron beam pipe. With such an optical cavity, a continuous laser power equivalent to 5 kW, much higher than those commercially available, can be achieved, leading to one backscattered photon per bunch crossing. This “few-ph...
متن کاملLuminosity Upgrade of Hera
After six years of operation the electron proton collider HERA had reached a luminosity of 1:4 10 cm s , very close to the design value. We present an overview on the HERA upgrade project that pursues the goal to further increase the luminosity three-fold by the year 2000. The increase is achieved by reducing the beam cross sections at the IP to 120 30 m (RMS values). If furthermore design curr...
