in KEK-PS main ring and has been examined using proton beam. At the conference, recent preliminary results of
experiments will be reported.
Design and Fabrication of Ion Beam Sputtering System with 10 KEV Energy
An ion beam sputtering coaters with a Kaufman
ion source for depositing thin and thick M.M. Larijani (New Affiliation Request Pending)
films has been constructed and successfully
operated. The cylindrical vacuum chamber is 66 cm length with an inner diameter 52 cm. The vacuum pressure of
9x 10 -4 Pa is obtained using a 32 m3/h rotary pump and a 400 lit/s turbo pump. A beam of different ion gas (H2,
O2, CH4, N2,…) was produced by ion source, with 5 cm diameter and 10 keV energy, by which the targets fixed on
the grounded holder were sputtered. Then the sputtered atoms were deposited on the substrates settled under the
target holder. The construction of different components such as ion source cooling system target holder and so on
will be describe, followed discussion of particular features thereof. The dependence of the ion current density on the
applied energy and the pressure will be studied too.
Beam Emittance Measurement of Dragon-I Linear Induction Accelerator
A beam emittance diagnostic system of an
intense pulsed electron beam (20MeV, 2.6kA,
80ns) based on optical transition radiation is

developed. A gated CCD camera is used to get time-resolved result. We develop a timing system to avoid the
time jitter, an anti-interference system to avoid the electromagnetic interference, and a C++ code to deal with the
experimental data.

The measured emittance is about 2000¦Ð.mm.mrad, which is agree with the result of three
Beam Current Monitor and Beam Position Monitor for PEFP LEBT
This paper describes the development status
of the beam current monitor and beam po- S.-H. Han, Y.-S. Cho, J.-H. Jang, H.-J. Kwon (KAERI)
sition monitor for the PEFP LEBT. For beam
current measurement, AC current transformer (ACCT) from Bergoz is integrated into a cautious shielding enclosure
in order to provide a wide dynamic range above 1E3. A beam position measurement system with four segmented
electrodes using secondary electron signal is designed and also give beam size information in front of RFQ. The
performance of the diagnostics including electron trap on the beam line is presented.
A Monolithic PBPM Capable of Measuring Photon Beam Angles
A photon beam position monitor (PBPM) designed
and manufactured into a new me- K.H. Gil, C.W. Chung (PAL)
chanical structure is in operation at the high
flux macromolecular X-ray crystallography (HFMX) beamline of the Pohang Light Source. The objective of this PBPM
is to make it possible to measure the vertical position, the horizontal position and the vertical angle of photon beams
