Fixed Target

Colliding Beam

4

• Advantages– zero charge system, suitable for creating new particles– well-understood beam properties– symmetric beams between the electrons and positrons– backgrounds low and well-undercontrol– good precision

• Disadvantages– large beam radiation– difficult to get a high luminosity

Electron and Positron Colliders

5

• Advantages– high c.m. energy– high luminoscity– Multiple (strong, electroweak) channels

• Disadvantages– initial state unknown– final state is difficult to read– not good precision

In 1996, the high energy physics community does not exist in Thailand according to the ranking by SCImago Journal & Country Rank (SJR).

From 19961

The table shows the result in 1996.

Our growth since 1996.

Comparing with our neighbors.

There has been substantial growth of physics research in Thailand since 2003.

Physics communities in Thailand

• The Thailand Center of Excellence in Physics, ThEP Center, is a collaboration of more than 12 Thai universities around the country.

How to set up LHC GRID site?

The basic LCG site consists of• UI User Interface • CE Compute Element • WN Worker Nodes• SE Storage Element • Site BDII Berkley Database Information Index• MON Monitor • Accounting service

Operating system SLC5

Middleware

• The gLite middleware is produced by the EGEE project.

Details for each hosts

• Host 1. Site BDII and CE • Host 2. SE • Host 3. WN • Host 4. UI and MON

All hosts are needed to install both SLC5and gLite.

Security requirements

• Personal Certificate Authorities (CA) for each users• HOST Certificate Authorities for each hosts

This can be issued by National Electronics and Computer Technology Center (NECTEC), THAILAND.

Software framework• Phedex Framework used by CMS• Ganglia Framework used by ATLAS• ALiEn Framework used by ALICE Environment• Root Basic collision software• Xrootd grid file system for ALICE• Dcache grid file system for CMS and ATLAS
