英文摘要：

In order to fully exploit the physics potential of the ILC, it will be necessary to measure (and control) beam parameters to a permille level precision. In case of the beam polarisation, this can only be achieved with dedicated high energy Compton polarimeters and by improving the detector linearity, as well as the calibration of the analyzing power. This note summarises results of an early testbeam period with the Cherenkov detector of the SLD polarimeter, linearity measurements of readout electronics and photodetectors and compares simulation results of the SLD Cherenkov detector with those of a new `U-shaped' prototype.

Design and Construction of a Cherenkov Detector for Compton Polarimetry at the ILC

This paper describes the design and construction of a Cherenkov detector conceived with regard to high energy Compton polarimeters for the International Linear Collider, where beam diagnostic systems of unprecedented precision must complement the interaction region detectors to pursue an ambitious physics programme. Besides the design of a prototype Cherenkov detector, detailed simulation studies are presented. Results of a first testbeam campaign with the main objective of validating the simulation in terms of the light distribution inside the channels and the channel response are presented. …

Precision Polarimetry at the ILC: Concepts, Simulations and experiments

The precision physics program of the ILC requires precise knowledge of the state of beam polarisation. In fact the Compton polarimeters intended for the ILC will have to measure the polarisation with error a factor of 2 smaller than the previous best measurement at the SLAC SLD experiment. In order to further reduce measurement error, spin tracking simulations in the ILC Beam Delivery System subject to ground motion induced misalignment have been performed and the expected variation in polarisation has been quantified. A prototype of a high precision spectrometer to record Compton scattered el…

Polarimetry at the ILC

At the ILC, the luminosity-weighted average polarization at the IP needs to be determined at the permille-level. In order to reach this goal, the combined information from the polarimeter and the collision data is required. In this study, a unified approach will be presented, which for the first time combines the cross section measurements with the expected constraints from the polarimeters. Hereby, the statistical and systematical uncertainties are taken into account, including their correlations. This study shows that a fast spin flip frequency is required because it easily reduces the syste…

Test Stand Measurements for an ILC Polarimeter

The setup of two different small scale teststands for measurements regarding an electron Cherenkov detector as part of the ILC polarimeters is presented. Component measurements already carried out are analyzed and others, foreseen for the near future, are discussed. The larger one of the two teststands features the old Cherenkov detector of the SLD experiment, which will be used as a reference for a number of crucial measurements. Especially, the requirements for the non-linearity of the read-out chain are studied in greater detail and methods for its precise measurement before and during oper…

A Quartz Cherenkov Detector for Compton-Polarimetry at Future e+e- Colliders

Precision polarimetry is essential for future e+ e- colliders and requires Compton polarimeters designed for negligible statistical uncertainties. In this paper, we discuss the design and construction of a quartz Cherenkov detector for such Compton polarimeters. The detector concept has been developed with regard to the main systematic uncertainties of the polarisation measurements, namely the linearity of the detector response and detector alignment. Simulation studies presented here imply that the light yield reachable by using quartz as Cherenkov medium allows to resolve in the Cherenkov ph…

Simulation Studies and Detector Scenarios for an ILC Polarimeter

High energy longitudinal electron polarimetry will be based on Compton scattering for the International Linear Collider. An unobtrusive measurement has to include a magnet chicane setup serving as a spectrometer. Current proposals make use of Cerenkov detectors for electron detection. A fast simulation has been developed to study the basic properties of scenarios for the polarimeter setup.

Precision Polarimetry at the International Linear Collider

The International Linear Collider (ILC) will collide polarised electrons and positrons at beam energies of 45.6 GeV to 250 GeV and optionally up to 500 GeV. To fully exploit the physics potential of this machine, not only the luminosity and beam energy have to be known precisely, but also the polarisation of the particles has to be measured with an unprecedented precision of dP/P ~ 0.25% for both beams. An overall concept of high precision polarisation measurements at high beam energies will be presented. The focus will be on the polarimeters (up- and downstream of the e+e- interaction point) …

A Calibration System for Compton Polarimetry at $e^+e^-$ Linear Colliders

Polarimetry with permille-level precision is essential for future electron-positron linear colliders. Compton polarimeters can reach negligible statistical uncertainties within seconds of measurement time. The dominating systematic uncertainties originate from the response and alignment of the detector which records the Compton scattered electrons. The robust baseline technology for the Compton polarimeters foreseen at future linear colliders is based on an array of gas Cherenkov detectors read out by photomultipliers. In this paper, we will present a calibration method which promises to monit…

Cherenkov Detector Prototype & Testbeam 2009

Precise knowledge of all beam parameters is crucial to fully exploit the physics potential of the International Linear Collider (ILC). A sufficiently accurate measurement of the beam polarisation can only be achieved using dedicated high energy Compton polarimeters combined with well-designed arrays of Cherenkov detectors. This note focuses on the design and detailed simulation of a suitable Cherenkov detector prototype and provides an overview of first results from a highly successful beam test period.
