the last MAC-meeting. It has been decided to use the DBA
as the lattice for the TPS, all straight sections have been
increased, the injector shall be a concentric ring sharing
the storage ring tunnel and there will be an overhead
crane. The MAC agreed with these decisions allowing
concentration on more detailed studies.
The MAC is expecting a further discussion during the
next meeting. Specifically, the MAC is now eager to learn
more about the management plans for this project, the
TPS project manager, budget, cost estimates, schedules,
and milestones to the extent that they impact directly the
health of the TPS project.
out that "As the particle shred size down to nano scale
using NanoCocrystallineOlivine technology (LFP-NCOTEC),
the powder coating becomes a problem". To solve the
coating problem, Aleees tried to make the secondary
particle to 15 µm in dimension, which included the primary
particle about 100 nm ~ 200 nm. This morphology not
only has better conductivity but also stores more power in
the same volume.
Following the workshop, there was a brief ceremony
for signing of the MOU. The CEO of Aleees, Mr. Jack
Wang, re-stated the philosophy behind Aleees battery,
Human Safe and Eco Friendly, as the driving force for
their innovation and a dream for turning the polluted
environment into a green land for future generations. Dr.
Keng Liang, director of the NSRRC, echoed such message
and confirmed NSRRC's support for domestic researchers
who are determined to pursue such technology
breakthrough. The collaborative agreement between
Aleees and NSRRC was the first industrial agreement
achieved by NSRRC’s Industrial Application Office, which
was formed in August 2007.

NSRRC Evaluates EPICS as the Possible Choice for its
Future Accelerator
An EPICS (Experimental Physics and Industrial Control
System) training course is held to give control specialists
an overview of its implementations in the control system
of the accelerator from February 18 to 27. NSRRC staff of
the Instrumentation & Control Group (IC group), RF Group,
and Beamline Group have geared up on putting plans and
tasks in place for Taiwan Photon Source (TPS), the next
accelerator that is presently scheduled to have groundbreaking
construction at around the end of 2009.
One of the key agenda is to fully evaluate available
software that will be adopted as the backbone of the
control systems for the accelerator. Programs include
lectures, which are offered by a service provider, and
intensive hand-on experiments. Staff has run through
examples to build prototypes and to simulate the
control system with parameters designed for the future
accelerator.
speed up the processing of experimental data of NSRRC
users, was offered on March 6. Getting new users to learn
old tricks is one of the tasks the NSRRC beamline managers
deal with every single day. Facing the increasing number
of users each year that leads to shorter time slot granted to
each research team, solutions were compiled and carried
out in recent months. As a result, users see more hand-on
training offered by NSRRC staff beginning 2008.
30 students in the class were required to study the
class material and to download the needed programs
beforehand. The course began with the installation of
GSAS and EXPGUI. Next, each person used their own XRD
experimental data to feed the systems for exercise. To run
the programs, each trainee is also required to gather cell
parameters, space group, and atomic coordinates as inputs.
If unavailable, the built-in examples were then used
instead.
The training course produced a set of feedback and
hit-and-miss score cards for fitting into the review process
of a (or more) programmable software solutions of the
control systems.

A technical review meeting of TPS
A technical review meeting for reviewing the detailed
design of the vacuum system for the Taiwan Photon
Source (TPS) was held on October 23, at High Energy
Accelerator Research Organization (KEK), Tsukuba, Japan.
The vacuum experts from the facilities of SPring-8, PF, PF-
AR, KEK B-Factory, J-PARC, and Univ. of Tokyo were invited
to attend the meeting. After five presentations on TPS
by the members of vacuum group of NSRRC and one
invited talk on pulsed sextupole magnet (PSM) by Prof.
H. Takaki of ISSP of Univ. Tokyo, the reviewing members
were much impressed by the thoroughness and quality
of the planning and the design of the vacuum system.
They also encouraged the team to complete the design
by improving the conceptual designs with real ones
according to the detailed specifications as possible since
the design criteria presented were appropriate.

First stage review of the Letter of Interest for TPS
After several discussions with the users and the
representing committee, the phase-I (up to year 2013)
planning of the Taiwan Photon Source project (TPS) has
gradually developed. In August 2008, NSRRC has sent out
the “Call for Letter of Interest (LOI)” announcement via
e-mail to universities and main research institutions. And
interested party was asked to submit the LOI in the name
of the organization. By the end of September 2008, a
total of 12 LOIs have been received from Academia Sinica,
National Taiwan University, National Tsing Hua University,

National Cheng Kung University, and Tunghai University.
After the first round of review by international experts
specialized in beamlines in December 2008, 11 out of 12
LOIs have been accepted for second stage review.
The second stage review of the LOI was completed
at the Science Advisory Committee (SAC) meeting held at
NSRRC in January 2009. The committee has scheduled to
perform the third stage review in September 2009 and a
final confirmation shall be made for the 5 beamlines for
phase-I planning.
of liquid helium during cavity operation. The construction
of a new cryogenic system with a refrigeration capacity
of 700 W is planned to cool all superconducting cavities.
The 700W cryogenic system was contracted out to Linde
in January 2009 and the delivery of the new cryogenic
system is foreseen to be in May 2011. Acceptance test of
the system will be finished in December 2011.

Purchasing order made for 3 main systems of TPS
During the end of 2008 and the beginning of 2009,
the purchasing order for three main systems of TPS, which
included the linac, the RF transmitter, and the cryogenic
system, has been made.
The linac consists of an electron gun, focusing and
bunching section, and accelerating section. The electron
gun is capable of providing pulsed nano-second electrons
with energy of 90 keV. Then, the electrons are further
focused and longitudinally bunched and transferred to the
accelerating section. The 20 meters accelerating section
is composed of three accelerating structures, equipping
with three high-power microwave amplifiers, in which the
electrons are accelerated close to the speed of light with
energy of 150 MeV. The linac was contracted to ACCEL in
November 2008.
The RF transmitter is the high-power source of the
RF system. It mainly consists of klystron, high-voltage
power supply, electronics and protection circuits. The
switching type high-voltage power supply benefits the
operation reliability and thus is selected. Three 500-MHz
RF transmitters, each with capacity above 250 kW, are
foreseen for the first-stage operation of the TPS storage
ring. Two 300-kW transmitters were contracted to THALES
in November.
In the TPS project, the installation of four 500 MHz
superconducting cavities of the single-cell type is planned.
Each cavity cryostat has a volume of 500 l and stores 400 l
