Auger Collaboration Meeting Report

Auger Collaboration Meeting Report

• ???

Status of Detectors

• As of Dec. 2004,
• 562 surface detectors (SD) are taking data
• 616 stations are deployed in the field
• Deployment rate is limited by the ability to
  deliver water to the tanks in the field
• (72 per month)

Collaboration Meeting Discussion Items

• Angular Accuracy
• Fluorescence Detector (FD) energy determination
  and systems
• SD energy determination and systems
• FD/Hybrid Analysis and Alignment
• Elongation Rate and SD Composition
• Horizontal Showers
• Anisotropy
• Auger North
• Upgrade Plan

Some Highlights of Science

• Based on gt1 year data
• So far there seems to be no strong signal toward
  the GC (very strong)
• There appears to be no correlation with the
  BLAZARs
• Data have been analyzed by Chicago group and UCLA
  group to obtain the spectrum at high energy not
  enough to support HIRES or AGASA result yet.

Meeting with important people

• Korea is welcome to join the collaboration
• Contribution of 100,000 per year would be
  minimum (plus 3000/person/year)
• Cash for water tank would be most valuable, but
  there are other possibilities (e.g., coaxial
  cable from PMT to electronic box)

Personal Impression on COREA

• Joining AUGER project seems to be absolutely
  necessary since,
• (1) Hardware fabrication appears to be
  difficult, but can be done
• (2) Software data analysis would be very
  complicated and we need to train ourselves with
  the help of the experts
• (3) Competition in high end of energy seems to
  be difficult, and we could concentrate on lower
  energy band
