Steering Meeting

• All activity that would interrupt normal data
  taking must be scheduled and approved by Masayuki
  Koga (Tohoku) and Brian Fujikawa (LBNL)
• Calibration source deployment
• Electronics maintenance
• Weekly steering meeting
• Summary is sent to all collaborators

On-site Computing Facilities

• Tohoku University if performing all of their
  analysis in Sendai
• Seventeen 850 MHz PIII PCs 800 GB disk for DAQ
• Four Dual 2 GHz P4 PCs 650 GB disk for Event
  Building
• Three IBM RS/6000 for run monitoring, tape
  copying, file serving
• Fifteen 800 MHz PIII PCs NFS 50 GB disk
• There are no on-site computers for analysis of
  raw data

10
US On-site Analysis Computer

• Dual 1.6 GHz Athlon PC
• 1.2 TB RAID
• LTO Drive
• Gigabit Ethernet

11
Permanent US Presence at KamLAND

• Alabama 1 Post-Doc (Calibration)
• Hawaii 1 Post-Doc
• LBNL 1 Staff Scientist (Infrastructure, FEE,
  Calibration)
• LSU 1 GS, PD, or Prof. in rotation (Calibration)
• Stanford 1 GS or PD in rotation (Trigger, FEE)
• TUNL 1 Post-Doc (Outer Detector)

12
Maintenance and Commissioning

• Additional US personal are required at the
  KamLAND site for short periods for maintenance
  and commissioning activities
• FEE upgrade and repair
• Installation of additional calibration source
  deployment hardware
• Commissioning of the 20-inch PMTs

13
Operation Shift Personal

• The primary function of the permanent on-site
  US personal is to support the US systems on
  KamLAND
• Operation shifts require at least 4 persons
• 2-4 additional US people are needed on-site to
  fulfill operation shift responsibilities

14
Administrative Support

• 1 part-time US secretary in Mozumi (Berkeley)
• 1 part-time US secretary in Sendai (Alabama, TUNL)

15
Facilities in Mozumi

• ICRR Dormitory (meals and/or lodging)
• Apartments
• No restaurants
• No markets

16
Local Transportation

• About 20 km from Osawano to Mozumi
• 2 mine vehicles (Toyota Land Cruisers)
• Private vehicles

  (air) ? Toyama
• US (air) ? Tokyo-Narita (train) ? Toyama
• US (air) ? Osaka-Kansai (train) ? Toyama
• US (air) ? Seoul (air) ? Toyama
• About 1200 round trip from the US west coast

19
Activities in Sendai

• All of the Japanese analysis is being performed
  at the Tohoku University in Sendai
• Data transfer to the US (will finish in a few
  months)
• Meetings and discussions
• Sendai is about 5 hours by train or 7 hours by
  automobile from Mozumi

Summary

• KamLAND is in operating mode
• Data taking is going pretty smoothly
• Need US people on-site for operation shifts
• Need US people on-site for support and
  maintenance of US components
