Development on Pulsed Laser Wire for Measurement of Beam Profile (original) (raw)
Production and handling of low emittance beam is important technology for linear colliders. For the view point of high energy experiments, luminosity and energy of collider is very important. So damping ring generates low emittance beam by radiation damping process. The advent of laser based beam profile monitor has increased the scope of studying low emittance beam dynamics. An Accelerator Test Facility (ATF) was built at KEK in hope of developing techniques for the low emittance beam. It consists of an electron linac, a damping ring in which beam emittance is reduced and an extraction line. The damping ring has two arc sections and two straight sections. 4 pm –rad vertical emittance was already confirmed by CW laser wire monitor at the ATF damping ring. The main goal of ATF damping ring was production of 10 pm-rad emittance beam stably with multibunch beam of 210 mA. In the damping ring at ATF, vertical beam size is less than 10 μm. For emittance measurement we are developing a ne...

Measurement of a small vertical emittance with a laser wire beam profile monitor
Physical Review Special Topics - Accelerators and Beams, 2002
We describe in this paper a measurement of vertical emittance in the Accelerator Test Facility (ATF) damping ring at KEK with a laser wire beam profile monitor. This monitor is based on the Compton scattering process of electrons with a laser light target which is produced by injecting a cw laser beam into a Fabry-Perot optical cavity. We installed the monitor at a straight section of the damping ring and measured the vertical emittance with three different ring conditions. In all cases, the ATF ring was operated at 1.28 GeV in a single bunch mode. When the ring was tuned for ultralow emittance, the vertical emittance of " y 1:18 0:08 10 ÿ11 mrad was achieved. This shows that the ATF damping ring has realized its target value also vertically.
Physical Review Special Topics - Accelerators and Beams, 2003
We present the measurement results of electron beam emittance in the Accelerator Test Facility damping ring operated in multibunch modes. The measurements were carried out with an upgraded laser wire beam profile monitor. The monitor has now a vertical wire as well as a horizontal one and is able to make much faster measurements thanks to an increased effective laser power inside the cavity. The measured emittance shows no large bunch-to-bunch dependence in either the horizontal or vertical directions. The values of the vertical emittance are similar to those obtained in the single-bunch operation. The present results are an important step toward the realization of a high-energy linear collider.
Measurement of an electron beam size with a laser wire beam profile monitor
Physical Review Special Topics - Accelerators and Beams, 2001
We describe the first measurement of an electron beam size in the accelerator test facility damping ring at KEK with a laser wire beam profile monitor. This monitor is based upon the Compton scattering process of electrons with a laser light target, which is produced by injecting a cw laser beam into a Fabry-Pérot optical cavity. We have observed clear signals of the Compton scattered photons and confirmed that the observed energy spectrum as well as the count rate agree with the expected ones. From the measurement, we have deduced the vertical beam size s b to be 9.8 6 1.1 6 0.4 mm, where the first (second) error represents statistical (systematic) uncertainty. Various improvements are in progress to enhance the signal-to-noise ratio, which is essential for the detailed study of the beam dynamics.
Achievement of Ultralow Emittance Beam in the Accelerator Test Facility Damping Ring
Physical Review Letters, 2004
For high luminosity in electron-positron linear colliders, it is essential to generate low vertical emittance beams. We report on the smallest vertical emittance achieved in single-bunch-mode operation of the Accelerator Test Facility, which satisfies the requirement of the x-band linear collider. The emittances were measured with a laser-wire beam-profile monitor installed in the damping ring. The bunch length and the momentum spread of the beam were also recorded under the same conditions. The smallest vertical rms emittance measured at low intensity is 4 pm at a beam energy of 1.3 GeV, which corresponds to the normalized emittance of 1:0 1:0 ÿ8 m. It increases by a factor of 1.5 for a bunch intensity of 10 10 electrons. The measured data agreed to the calculation of intrabeam scattering within much better than a factor of 2.

A conceptual design work and a basic experimental study of a new beam profile monitor have been performed. The monitor will be used to measure emittance of an electron beam in the ATF damping ring at KEK, in which the transverse beam size of about 10 micron is expected. It utilizes a CW laser and an optical cavity, instead of
Compact Four Mirror Laser Wire System for Quick Measurement of Electron Beam Profile
2012
A compact prototype four mirror optical cavity is being constructed at KEK-ATF to measure a low-emittance electron beam in the damping ring. Length of four mirror rectangular cavity is 103 mm. Minimum beam waist depends on aspect ratio of resonator. In order to achieve the desire value of aspect ratio, distance between adjacent plane mirror and concave mirror are kept very small by using special mirror alignment scheme. Total cavity length of four mirror resonator is matched to pulse repetition of mode locked infra-red laser oscillator. Pulse repetition rate of mode locked laser oscillator is 714 MHz. Electron beam inside ATF Damping Ring has repetition rate of 357 MHz. Minimum beam waist is obtained in sagittal plane using IR pulsed laser. Electron beam scanning time can be reduced using such type of compact laser wire system. With very small laser beam size effective electron –photon collision can be observed. We report the development and performance studies of such type of compa...
Beam profile measurement for electron accelerators
Japanese Journal of Applied Physics, 1966
New methods have been developed for monitoring the beam profile of electron accelerators. For electron energies above and below 3 MeV, the monitor utilizes the secondary emission from the probe and the partial absorption of the primary beam in it, respectively, and the probe consists of copper wire or thin aluminum plate. The performance of the monitor was investigated with electron beams of a 15 MeV linear accelerator and a 2 MeV resonance transformer. The advantages of these methods are their simpleness and utility for high power accelerators.

In 2009 a beam-energy monitor was installed in the high energy beam transport (HEBT) line at the Brookhaven National Lab linac. This device measures the energies of electrons stripped from the 40mA H beam by background gas. Electrons are stripped by the 2.0x10torr residual gas at a rate of 1.5x10/cm. Since beam electrons have the same velocities as beam protons,
R&D towards a laser based beam size monitor for the future linear collider
Laser wires will play an important role as the standard monitor for beam size measurements with micrometre res-olution for the beam delivery system at any future linear collider. Some R&D work is still necessary to elevate pre-liminary laser wire designs to a compact, non-invasive and fast-scanning device. In this paper the latest R&D together with recent measurements and simulations are presented. Schemes to measure the beam size in a bunch train and from train-to-train are presented together with an evalu-ation of scanning techniques meeting these requirements. Results from simulations and measurements with a laser focus system and of a proposed Compton calorimeter are reported. Furthermore plans are outlined for the installation of a fast laser wire experiment at the PETRA accelerator at DESY.
