## Proposal A · Directional frequency response
Compare similar clocks or optical systems differentially, using repeatable orientation changes or known background modulation. First calculate ASD and comparison signals for the actual apparatus.
## Proposal B · Moving charges
Specify source bunches, transverse separation, probe properties and effective bandwidth. Treat fields and forces separately and publish a normalization and calibration scheme.
## Proposal C · Longitudinal disturbance detection
Build a transfer function from the longitudinal field to a measurable quantity. Use multiple channels, control geometry or controlled excitation to separate candidate signals from environmental correlations.
## Common deliverables
Every proposal needs a question, equations, signal estimate, noise spectrum, calibration, blind-analysis strategy and failure criterion. This page does not imply facility access or collaboration commitments.
