## Specific Goals for 2008 (1)

**Beam-beam Simulations **
- Wire Compensation: Predictions and bench marking with data from experiments
-  Calculations of lifetime from solutions of the diffusion equation, comparison with data
- LHC: Effect of wire compensation, benefits to luminosity
- LHC: Impact of crab cavity on luminosity
**Crystal Collimation**
- Perform realistic full-scale simulations.
- Replace crystal and goniometer in the Tevatron with new/improved ones.
- Install enhanced beam diagnostics.
- Perform measurements of channeling, volume reflection and collimation efficiency with these new installations.

## Specific goals for 2008 (2) 

**Electron-lens compensation**
- Design, build, test and commission the Gaussian (modified Gaussian) electron gun.
- Simulations to verify that Gaussian e-beam profile improves p/pbar lifetime and reduces diffusion rates
- Beam-beam compensation studies in the Tevatron
-    - effect of electron beam size on proton lifetime
-    -  effect of low frequency e-current variation on proton lifetime
-    - demonstrate pbar tune spread reduction
-    - lifetime improvement vs e-current
**Schottky Monitor**
- Design and test the control interface to the Schottky hardware.
- Return hardware to CERN and test in the tunnel later in the spring

## Specific goals for 2008 (3)

**Chromaticity tracker and feedback**
- Participate in the chromaticity feedback studies at BNL.
- Travel to CERN in the summer, in preparation for LHC commissioning.
**Joint IR studies**
**  **Optics layout with Nb3Sn magnets in the inner triplet for the Phase I and Phase II upgrades.
-  Energy deposition studies with Nb3Sn magnets

## Specific goals for 2008 (4)

**Injector Studies**
- Space charge simulation studies for the new PS Booster.
- Provide support for ESME simulations.
- Benchmarking with Booster data (?)
**Beam Commissioning**
- Join the LHC commissioning team
**Hardware Commissioning**
- Planning and execution of the cool down and powering of IR magnets
