Table of Contents
Some questions from Lecture 1 (Berg):
- Why are the dots on the “Diagnostics in focal plane of Spectrometer” so evenly spaced?
- What is the real world example of measuring emittance?
- (2) Describe the focal plane diagnostics of the spectrometer in more detail
- (2) l doesn't appear to have a dependence on anything. Can you clarify how l(t) transforms? How exactly is l define?
- Can you show a (x|a)!=0 case
- (4) Why is sigma matrix symmetric? What is definition of sigma_21? How do we create the 6×6 ellipse matrix?
- How does the x-Theta measurement setup look like (measure orientation of ellipse)
- Definition of Louisville Theorem?
- How do we define the central ray?
- R11, R12, R21, R22 - can more than one be zero?
Some questions from Lecture 2 (Couder):
- Does the kinematics calculator include anisotropic gamma radiation?
- Why is the angular acceptance fixed?
- Beam spot and divergence in front of target, focusing necessary to minimize (x|a)?
- If (x|a) is non zero, how does that affect the resolving power?
- Rejection requirements were unclear
- Is x_0 the half beam spot size?
- definition of rejection for detectors
- What is the meaning of the interpolation line of the charge state distribution?
- Are separators ever compromised by space charge effects from large beam currents?
- What limits the systematic errors in measurement efficiency, transmission, charge state population?
- How significant can be the background in a (p,g) experiment from target impurities?
- Notation: is there a difference between (x|d)d_1, (x,m)dM/M, and (x|\Delta M) \Delta M/M?
Some questions from Lecture 3 (Berg):
- 1) Does COSY allow implementation of higher order corrections in dipoles?
- 2) Why dipoles doublets instead of one large dipole?
- 3) Definition of K, T, and C in dispersion matching.
- 4) Define fringe field.
- 5) Define Rogowski profile.
- 6) Explain H and K coil in K600 Spectrometer. Why quad inside K600?
- 7) HO in K600 Spectrometer.
- 8) How to use reconstruct the scattering angle at target from focal plane measurement? Setup of multi-slit for angle calibration, drift between target and multi-slit.
- 9) Discuss only one spectrometer (e.g. K600, Grand Raiden, Big Karl).
- 10) Explain magnetization of ferro-magnetic material.
- 11) p. 14 Why not 0 deg with beam (for dispersion matching)?
- 12) Will permanent magnet saturate material. Similar to coil generated fields?
- 13) Why is dispersion matching needed?
- 14) Can EFL be measured?
