Complaints (and solutions!)

• Elemental maps are nice, but...
• Why not map ratios to emphasise correlations?
• Why not always include SEM/Optical image?
• Greater use of visualisation software
• Struggle with statistics
• Need bigger detectors!
• More intense beams!
• DAQ systems that dont fall over for gt5kHz!

9
More Complaints...

• Spot size stuck at 1 (0.4) micron since 1981
• See previous solution
• Need reliable, commercially available high
  brightness ion sources
• Insufficient use of internet
• Tap into specialist expertise

10
One More Complaint

• Important review books on analytical techniques
  rarely mention the nuclear microprobe!
• More contact with influential people in
  specialist fields.

11

To be released
14
MARC

• Upgrade voltage divider with resistors
• Improve gas handling
• Terminal stabilisation
• More SF6 gas
• Improve brightness

15
Melbourne Beam Brightness

• Measured with a suppressed Faraday cup just
  upstream of specimen chamber.
• No additional beam for half divergences greater
  than 0.23 mrad.
• Absolute value of brightness a function of
  machine configuration.
• Brightness profile always the same.
• Strong peaking always observed.
