  1. Jicamarca in Review The Jicamarca Radio Observatory Near Lima, Peru By Jorge Chau and Ronald Woodman (IGP) Donald T. Farley and Wesley E. Swartz (ECE-CU) David Hysell (EAS-CU) Swartz 03/11/7 2003 November NSF Panel Review of Jicamarca

  2. Jicamarca in Review, 1999-2003 • An Introduction to Jicamarca (DTF) • Management Overview and Changes - people (DTF) • Science Highlights - ideas (DLH) • Infrastructure Development - tools (JLC) • Other Instruments/projects (JLC) • Outreach, Education, Societal Impact (WES) • Response to the Last Panel’s Report (WES/DTF) • Maintenance Challenges (JLC? Or WES?) • Budget Challenges (WES) • The Next Five Years (DLH) 2003 November NSF Panel Review of Jicamarca

  3. Maintenance Challenges • Lots of electronics • Lots of antenna connections (corrosion) • Aging vehicles • But, there are really no single-point failure modes (baring some cataclysmic event) that would cause an extended down time: Multiple systems with multiple transmitters, receivers, computers, but final transmitter tubes now run about $80,000 2003 November NSF Panel Review of Jicamarca

  4. Budget Challenges • Additional operational costs for new instruments • JULIA – cost was not previously included in the main budget • SOUSY – fuel expected to be $8K/yr for 500 hours of operation • Bistatic – Equipment funded separately; routine operational costs • Operating with 4 big transmitters – increases peak demand billing • Replacement of aging vehicles • Need a new one approximately every 2 years • Replacement of any failure of transmitter tubes • $15K for drivers (expected lifetime is 15K hours: 2 at 13K hr, 1 at 3K hr) • $80K for finals (expected lifetime is 15K hours: 2 at 13K hr, 1 at 3K hr) • $40K for SOUSY finals 2003 November NSF Panel Review of Jicamarca

  5. Broad Category Budget Breakdown The fine print: Proposed for 2004-2005: $1.5M (with wish list items) 2003 November NSF Panel Review of Jicamarca

  6. Budget Wish List • Electronic steering of main array (top priority) • 128 – phase switches plus control ($120…split over 3 years) • Restoration of electronic steering of SOUSY radar • 4-phase selection option $30K • 8-phase selection option (original) $45K • Spare transmitter tubes • 1.5-MW Main Transmitter Final: $80K • 100-KW Main Transmitter Driver (4CX4000G): $15K • 300-KW SOUSY Final: $40K • Misc. • Lab equipment • Computers and networking equipment to stay current 2003 November NSF Panel Review of Jicamarca

  7. Wish List in Perspective Highest priority on bottom 2003 November NSF Panel Review of Jicamarca

  8. Bare-Bones Wish List But Retaining Electronic Steering of Main Beam Highest priority on bottom Subject to no transmitter failures in first three years. 2003 November NSF Panel Review of Jicamarca

  9. Bare-Bones Wish List Modified by a Transmitter Failure Highest priority on bottom 2003 November NSF Panel Review of Jicamarca

  10. Proposed Yearly Budget Distribution 2003 November NSF Panel Review of Jicamarca

  11. Budget in Perspective Partial Year 2003 November NSF Panel Review of Jicamarca

  12. Last 2003 November NSF Panel Review of Jicamarca
