2. CLEO-c and Precision Test of the Standard Model
A triangle only if there are 3 quark generations
Precision depends both on experimental and theoretical uncertainties

3. CLEO-c: Tests of the Standard Model and QCD
CLEO-c goals:
Significant improvement of Charm measurements to constrain the Standard Model.
PDG = present accuracy
Test of LQCD (Lattice QCD): Necessary to give theory constraints for precision tests of the Standard Model
Present results from CLEO-c with fraction of expected data

4. CLEO-c Impact on the Unitarity Triangle
Now: Theory uncertainties dominate
With few % theory
& experimental errors made
possible by CLEO-c and 500 fb-1 each from the B factories:

7. ILC Tracking Simulations
ILC Accelerator Projects
Damping Ring Studies
CESR is currently the highest energy wiggler-dominated storage ring in the world, and operates at energies very close to those of LC damping rings (a few GeV). After it shuts down for HEP, running time will be equally shared between CHESS and ILC damping ring studies.

RF Cavity Technology
In May 2006, after undergoing a buffered chemical polishing (BCP) treatment at Cornell University, the first US purchased, processed and tested International Linear Collider superconducting cavity achieved a milestone accelerating gradient of 26 MV/m (megavolts per meter). The design goal is 35 MV/m. This accomplishment was a first test for the US facilities for ILC.
ILC Tracking Simulations
Working with Cornell HEP faculty, the group aims to simulate the tracking of the beam from the source to the collision point.
Positron Source Studies
Including Polarized beams

8. Energy Recovery Linac (ERL) New Synchrotron Light Source
ERL properties:
* ☼ times brighter than any existing synchrotron light source
* mamp average current
* Mhz pulse rate with 2 psec(10-12 sec) pulse width
(plan to compress to 0.1 psec width)
* Superconducting RF accelerating cavities
ERL Funding (prototype)
NSF $18 Million
Cornell--- $10 Million
NY State--- $12 Million
Making his second visit to the Cornell campus in a week, New York Gov. George Pataki again brought funding, this time $12 million for preliminary work on the proposed Energy Recovery Linac (ERL)
Full funding $400 Million in
Spring 2008

9. ERL Prototype Successfully Tested
kV Photoemission Gun
View from beam dump to gun
Test beam successfully brought from gun to beamdump
Gun operating voltage was 250 kV
Gun current only several μ-amp due to low power laser
