## Main Injector Deceleration

- These deceleration studies occurred in 2000, consuming 8 parasitic accelerator study sessions and 27 hours.
- A beam momentum of 3GeV/c was achieved without any accelerator hardware modifications.
- Note the red RF glitches, and accompanying green beam intensity losses.

## Deceleration Efficiency

- Beam Intensity with RF Glitch

- Beam Intensity without RF Glitch

- Beam Momentum

- RF Bucket Area

- These simulation results agree very well with the experiment

## MI-10 Extraction

- 	The materials for the MI-8 xfer line switch magnet (2 GeV/c) have been purchased, and the laminations have been stacked.  The stand needs to be finished and the coils wound.  The finished magnet with stand is offered as an in-kind contribution from Hbar Technologies, LLC.

## MI Extraction Magnets & Lattice

## Antiproton Transfer Line

- Lattice design by David Johnson of FNAL for Hbar Tech

## Transfer Line Carrier Pipe

- Installed in 2001 for the speaker and paid for by private venture capital under a Work-for-Others Agreement

## Proposed Facility Location

## Preliminary Facility Design

- Design by FESS and Cost Estimate by Vic Kuchler of FNAL for Hbar Tech

## Degrader Optics

- The degrader material has already been purchased by Hbar, and will be loaned to the experiment as an in-kind contribution.
- The blue spectrometer magnet must be built (parts already purchased)
- The wedge degrader must be built (not in cost estimate)

**Spectrometer Magnet**

- Antiproton Distribution after the Degrader

## Wedge Magnet Design

## Spot Size at Wedge Focal Point

## Foil Internal to the Pbar Trap

- Because the HiPAT trap only has a 20keV electrostatic barrier potential, this broad energy distribution imposes the dominant antiproton loss mechanism.  The estimated survival fraction into HiPAT from 8 GeV is 5x10-4.

## NASA HiPAT Trap

- Hbar Tech is transporting this trap, along with its commissioning H- and H+ linacs and auxiliary cryo and vacuum hardware in the next months.

## Conclusions

- For the full facility civil construction scenario, the total project cost for the facility plus beamline is estimated to be $6.9 million (see information slides).
- For a stripped-down civil construction scenario in which a smaller underground enclosure is provided (along with power and water but no sewer), the total project cost for the facility plus beamline is estimated to be $3.9 million.
- This facility not only serves the needs of the proposed antimatter gravity experiment, but during commissioning many small scale experiments aimed at atomic and nuclear physics, medicine, defense, homeland security, nuclear propulsion for NASA’s return to Mars, and advanced deep-space propulsion R&D can be performed.

## Scope and Cost Estimate

- Given the nature of the beamline, no spares are needed and are not included in the cost estimate.
- If 1 GeV/c is the design momentum, permanent magnets are possible, which would reduce the project cost to $2.5 million (enclosure only scenario), down from $3.9 million.
