The DAΦNE Luminosity Monitor
نویسندگان
چکیده
DAΦNE, the Frascati Φ-factory, is an e+/e– collider with 2 interaction points (IPs). The center of mass energy is 1020 MeV and the design luminosity 4.2 × 1030 cm–2 s–1 in single bunch mode and 5 × 1032 cm–2 s–1 in multibunch mode. Between the possible electromagnetic reactions at the interaction point, single bremsstrahlung (SB) has been selected for the luminosity measurement. The SB high counting rate allows real-time monitoring, which is very useful during machine tune-up and moreover the narrow peak of the SB angular distribution makes the counting rate almost independent from the beam position at the IP. A description of the experimental set-up, calibration results and luminosity measurements is presented.

Luminosity Optimization in Daφne
DAΦNE the Frascati Φ-factory, started the two beams commissioning on March 1998. Since then a relevant amount of experience concerning the techniques and procedures for optimizing the luminosity has been acquired. All the schemes used are strongly based on the use of various diagnostic systems including a dedicated luminosity monitor, orbit measurement, tune monitor, synchrotron light monitor a...
متن کاملMeasurement of the luminosity at the DAφNE collider upgraded with the crab waist scheme
The test of the crab waist collision scheme, undergoing at the ee Frascati DAΦNE accelerator complex since February 2008, requires a fast and accurate measurement of the absolute luminosity, as well as a full characterization of the background conditions. Three different monitors, a Bhabha calorimeter, a Bhabha GEM tracker and a gamma bremsstrahlung proportional counter have been designed, test...

متن کاملBeam Position Monitor System of DAΦNE
The DAΦNE beam position monitor (BPM) system consists of 150 monitors installed all along the machine. Design issues, calibration procedures, experimental results and performance of the system are described. The closed orbit in the main rings is extracted from the BPM signals through narrowband receivers (realized by Bergoz Precision Beam Instrumentation for DAΦNE), then acquired and processed ...
متن کاملDa Φ Ne Operation and Plans for Da Φ Ne 2
The e+ecollider DAΦNE, a 1.02 GeV c.m. Φ-factory, has reached a peak luminosity of about 1.4x10 cm s and a peak integrated luminosity in one day of about 8.6 pb. With the current rates the physics program of the three main experiments DEAR, FINUDA and KLOE will be completed by the end of 2007. In this paper we describe in detail the steps which have led to the luminosity improvement and the opt...
