Prototype Test of Energy Doubler/Saver Bending Magnet

Compensation Scheme of Elliptical Polarization from Bending Magnet at SRRC

A prototype elliptical polarization from bending magnet ( EPBM) system with a dynamic local bump has been implemented at the SRRC storage ring. The local bump is created by using two pairs of vertical correctors located on each side of the bending. The bump strength coeffieient was obtained from measured beam response matrix. Disurbance of stored electron beam orbit was boserved while flipping ...

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Eddy Field Measurement by Using Search Coils for Bending Magnet

In order to estimate a field disturbance of a guiding field of a synchrotron due to an eddy current, magnetic fields in a bending magnet have been measured. The magnet was excited by a sinusoidal current with a repetition of 30 Hz. Two search coils were used in the measurements. One is a reference coil and the other is a measurement coil. An imaginary part of an eddy field was derived from phas...

Clinical evaluation of a prototype multi-bending peroral direct cholangioscope

BACKGROUND Although peroral direct cholangioscopy (PDCS) is emerging as an alternative to traditional mother-daughter cholangioscopy, it is associated with high failure rates. The aim of the present study was to evaluate the ability to insert and carry out interventions using a prototype multi-bending PDCS. PATIENTS AND METHODS Prospective, observational clinical feasibility study was done in...

dE/dx PROTOTYPE TEST*

A small prototype of a multiwire dE/dx detector was tested in SLAC's test beam. The basic concept of the detector was similar to the JADE drift cell design. The purpose of the test was to decide on some design parameters for a full size prototype, which is now in construction. Introduction Our motivation was to concentrate on the particle identification below 4 GeV/c which is about the limit of...
