Major Research Activities in Korea


The Belle experiment started in 1994 after long time studies

Letter of Intent submitted to the March 1994

Belle Detector Completed in 1999

Physics goals

CP – violation (Matter/Antimatter Ratio in B-meson Systems)

Rare decay studies ( Rare Particle Phenomena )

Many B particles are produced detail studies of B-meson systems as well as heavy quarks (including charm particles)

10 million particles to be studied large computing facilities and fast network connecting KEK and participating institutions are needed.

Many Important physics results : One of the highlights is

“Observation of large CP-violation in B-system”

Announced at the international symposium on the Lepton-Photon Physics in Rome, 2001.

Nearly at the same time as the announcement by its US competitor, BaBar Experiement at SLAC

Participation of Institutions in the HEP Data Grid Project

• Established in July 1, 2000. • A national center

designated by the Korean Ministry of Science and Technology and supported by the Korean Science and Engineering Foundation (KOSEF)

• 47 HEP physicists with doctoral degrees and 120 graduate students from 12 universities inside Korea.

• Major research activities:• CMS at CERN• AMS at ISS based at

CERN• Belle/K2K in Japan• CDF/Phenix in USA


TEIN Bandwidth requirement

– From CERN 100 MB/s experimental data trasfer

– 24 hrs/day, 10 million seconds/year operation

– Data Size =1 PetaBytes/y– MC data production(2 PB/

y) and transfer to Europe and USA

– Therefore we need 2.4 Gbps

• 800 Mbps (Exp Data)• 1600 Mbps (MC Data)

Considering other traffic, we need 10 Gbps.

Korea-Japan (alone) Bandwidth Requirement

KEK Experiments

– 130~370 Mbps by 2006

– 650 Mbps after 2006

Korea-Japan-USA Connection (additional)

– Fermilab CDF Exp. (40~230 Mbps)

– CMS Exp (800 Mbps)

–Total bandwidth requirement:

–1.2~1.6 Gbps Total of minimal 2.4 Gb

ps is required Considering other traffi

c, we need 10 Gbps


Traffic/Data for HEP experiments carried out in Traffic/Data for HEP experiments carried out in JapanJapan Belle Experiment

– At present, data of 30 Tbytes/year are being collected: 0.3 TB/day• It is approxmately 5~15 Mbytes/s, meaning 40 ~120 Mbps• Production and share of Monte Carlo simulated data (~3 times of real data) amo

ng Korea-Japan collaborators (file transfer)• Therefore, 120 Mbps~360 Mbps is needed (24 hrs/day operation, 25 millions s

econds in total operation per year)– After 2006, we expect collecting data at 220GHz amounting 2 PB data/year

• Koreans expect processing 30% of data (600 TB/year) 4800 Tb/30 Ms = 160 Mbps

• Monte Carlo data production and share with Japan (approx 1.8 PB/year) 480 Mbps

• Therefore, we need 640 Mbps between Japan-Korea for this experiment K2K Experiment

– Until 2001, we have approx. 830 GB of unprocessed data– Processed data size is 3.1 TB– Expect the same size of data in 2003– Monte Carlo Simulation Data is about 1.6TB – We need 2~3 Mbps

SuperKamiokande(Super-K) Experiment (Kamioka-near Toyama)– Collects approx. 27 Gbytes of data, needs 8*27 Gb/86.4 ks = 2.2 Mbps– About the same size of Monte Carlo data are produced– We need 5~6 Mbps


Bandwidth Requirements Korea-Japan-USABandwidth Requirements Korea-Japan-USA

Summary for Korea-Japan connection– 130~370 Mbps by 2006– 650 Mbps after 2006

When Genkai is extended to USA via Korea-Japan– CDF Experiment at Fermilab

• Run IIa(2001.3 - 2004) and Run IIb(after 2004 )– 500 Tbytes/year are produced (Run Iia), > 3 Pbytes (after 2004)

• Before 2004 : 10% processing (50 TBytes/year) : ~ 13 Mbps • After 2004 : 10% processing (300 TBytes/year) : ~ 76 Mbps • Monte Carlo Data Production and Transfer: twice the above • Before 2004 : 40 Mbps • After 2004 : 230 Mbps

– Data Transfer for CMS (Europe)• Monte Carlo Data Production and share with USA CMS Collaborators• 15 years from 2003, we share 1 Petabytes/year = 800 Mbps is needed

– Summary of Bandwidth requirement Year 2003 2004 2006

Between Korea-Japan 1200 1400 1650 MbpsBetween Japan-USA 840 1030 1030 Mbps

(for Korean traffic)


SuggestionsSuggestions

In Summary Minimal bandwidth requirements for the HEP research is

– 2.5 Gbps over Korea-Japan-USA– 2.5 Gbps over Korea-Europe

Suggest that if we use the Busan-Kyushu line for Korea-USA APII, we need the network to be 2.5 Gbps initially and then 10 Gbps at least reflecting other usage in near future.

Also we need TEIN to be 2.5 Gbps initially and then 10 Gbps as a separate network
