A set of two Inductive Pick-Up (IPU) prototypes with its associated electronics for Beam Position Monitoring (BPM) in the Test Beam Line (TBL) in the 3 rd Compact Linear Collider (CLIC) Test Facility (CTF3) at CERN were designed, constructed, characterized and tested by the IFIC team. One of this two prototypes is already mounted in the first modul...

... stability during deceleration. The TBL consists of a series of FODO lattice cells and a diagnostic section at the beginning and end of the line to determine the relevant beam parameters. Each cell is comprised of a quadrupole, a BPM (labeled as BPS) and a Power Extrac- tion and Transfer Structure (PETS) [1]. A 3D view of a TBL cell is shown in Fig. 1. The available space in CLEX allows the construction of up 16 cells with a length of 1.4 m per cell. The BPS's are IPU type and the expected perfor- mances for a TBL beam type (current range 1-32 A, energy 150 MeV, emittance 150 µm, bunch train duration 20-140 ns, microbunch spacing 83ps (12GHz), microbunch dura- tion 4-20 ps, ...

The Beam Position Monitors (BPM) are devices that can be used in every accelerator to provide information on the position of the beam. This paper reports the simulation and design of a re-entrant cavity BPM with its associated electronics to be used for IPM low energy electron Linac being developed at Institute for Research in Fundamental Sciences....
The main beam of the Compact LInear Collider (CLIC) requires the beam trajectory to be measured with 50 nm spatial resolution. It also requires a time resolution capable of making position measurements of the head and tail of the 156 ns long CLIC bunch train, for use in dispersion free steering based on an energy chirp applied along the train. For...

The European X-ray Free Electron Laser (E-XFEL) will use a total of ~300 button BPMs along the whole accelerator, and additionally 160 cavity BPMs. The pickups for the button BPMs have been designed by DESY, whereas the electronics has been developed by PSI. This paper gives an overview of the button BPM system, with focus on the RF front end elect...
Cold cavity BPM was developed to meet high position resolution and bunch to bunch measurement time. It is designed based on re-entrant cavity and has Low-Q to achieve short signal decay time in L-band frequency with large aperture as 78mm. The beam test was performed to demonstrate position resolution at ATF main linac, which is operating with 1.6n...
We describe the development of a new button-type beam position monitor (BPM) for the Brazilian Synchrotron Light Source (LNLS) storage ring. One third of the storage ring stripline BPMs have been replaced with this new model. We also present performance results.

The normalized ΔH, V /Σ signals have to show a good linear behavior for the beam position variation within the central region of the BPS aperture, so these output signals will be related to the beam position components by the linear relation: ...
A set of 17 Inductive Pick-Ups (IPU) for Beam Position Monitoring (BPM) with its associated electronics were de-signed, constructed and characterized at IFIC for the Test Beam Line (TBL) of the CLIC Test Facility (CTF3) at CERN. In October 2009 the full set of IPUs, labelled as BPS, was successfully installed in the TBL line. In this pa-per, we summarize the series production phases of the BPS units, focusing in the analysis derived from their charac-terization tests. A custom-made test bench used for the characterization tests based on the wire-method test for emulating the beam position was also described in detail. This test bench helped us to determine the performance pa-rameters at beam pulse time scale (from 100μs/10kHz to 10ns/100MHz), with high precision and in an automatized way for every unit of the BPS series.
