Technical Infrastructure Monitoring at CERN
The Technical Infrastructure Monitoring system
(TIM) is used to survey and control J. Stowisek, T.R. Riesco, A.S. Suwalska (CERN)
CERN’s technical services from the CERN
Control Centre (CCC). The system’s primary function is to provide CCC operators with reliable real-time information
about the state of the laboratory’s extensive and widely distributed technical infrastructure. TIM is also used to
monitor all general services required for the operation of the accelerator complex and the experiments. A flexible data
acquisition mechanism allows TIM to interface with a wide range of technically diverse installations, using industry
standard protocols wherever possible and custom designed solutions where needed. The complexity of the data
processing logic, including persistence, logging, alarm handling, command execution and the evaluation of datadriven
business rules is encapsulated in the system’s business layer. Users benefit from a suite of advanced graphical
applications adapted to operations (synoptic views, alarm consoles, data analysis tools etc.), system maintenance
and support. Complementary tools for configuration data management and historical data analysis will be available
before the start-up of the LHC in 2007.
Air Temperature Analysis and Control Improvement for the Technical Zone at TLS
This paper presents the air temperature
analysis and control improvement for the J.-C. Chang, J.-R. Chen, Z.-D. Tsai (NSRRC) M. Ke (NTUT)
technical zone, where many critical instrumentations
of power supply, rf, vacuum and control apparatuses are located, at the Taiwan Light Source (TLS). The
technical zone with circular shape is located on the core area of the storage ring. The diameter and height of the
technical zone are 28.5m and 3m, respectively. Totally 13 temperature sensors are installed in this zone to online record
the air temperature history. Because of insufficient cooling capacity and poor air circulation of the air-conditioning
(AC) system, the air temperature may reach to 30 degrees C, and spatial air temperature difference may be more than
8 degrees C. To cope with those problems, a computational fluid dynamics (CFD) code is applied to simulate the
spatial temperature distribution. The AC cooling capacity will be increased, and the air exits and exhaust distribution
will be modified according to the simulated results.
Design of the Utility System for the 3 GeV TPS Electron Storage Ring
After 13-year operation of the Taiwan Light
Source (TLS), National Synchrotron Radi- J.-C. Chang, J.-R. Chen, Y.-C. Lin, Y.-H. Liu, Z.-D. Tsai (NSRRC)
ation Research Center (NSRRC), had proposed
to construct a new light sourc, Taiwan Photon Source (TPS) in the near future. TPS is preliminarily designed
with 3.0 GeV in energy, 518.4m in circumference and 24 Double-Bend Achromat (DBA). This study designed the
utility system, including the electrical power system, grounding system, de-ionized cooling water (DIW) system and
air conditioning (AC) system for the TPS. Special considerations are focused on the stability of the electrical power
and grounding system and temperature control of the DIW and AC systems. The power and cooling loads had been
estimated according to each subsystem of the accelerator. Layouts of main utility equipment and piping system had
also been preliminarily designed.
