1. MARC and MARCO What does the future hold?

2. What are we doing? 270 Nuclear Microscopy, Nuclear Microprobe or Proton Microprobe papers 1993-October 1996

3. Where are we publishing? +3 books 270 Nuclear Microscopy, Nuclear Microprobe or Proton Microprobe papers 1993-October 1996

4. What about the last conference? 149 Presentations

5. What about IBA* in general? * Ion Beam Analysis From IBA-11 conference, 1993

6. Lateral Structure of Specimen Number of Papers Lateral Specimen Structure in Unfocused Beam Studies

7. What about other fields? u Nuclear microprobe papers270 u Ion Microprobe327 u Electron Microprobe732 u (Physics) Neutrino Oscillations157 u (Med) BRCA1 & BRCA2346 u (Geol) Cretaceous-Tertiary (KT) Boundary248 u (Eng) Fusion Power163 u Bose Condensation104 u Buckminsterfullerene1,175 u Polymerase Chain reaction22,509

8. Complaints (and solutions!) u Elemental maps are nice, but... –Why not map ratios to emphasise correlations? u Why not always include SEM/Optical image? –Greater use of visualisation software u Struggle with statistics –Need bigger detectors! –More intense beams! –DAQ systems that don’t fall over for >5kHz!

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

10. One More Complaint u Important review books on analytical techniques rarely mention the nuclear microprobe! –More contact with influential people in specialist fields.

11. MARC u Upgrade of MP2 u New Atomic Force Microscope u Upgrade of Pelletron accelerator u Rationalisation of computer system u New lenses for MP2

12. MARC u MP2 upgrade: –In chamber pre-amp –Move ion pumps under beam line –Install magnetic shielding –Modify chamber to allow shorter working distance –New microscope (Edmund) –Radical lens system

13. MARC u New Lens –Novel design –Strong –Sort working distance –MARC/CSIRO collaboration To be released

14. MARC u Upgrade voltage divider with resistors u Improve gas handling u Terminal stabilisation u More SF 6 gas u 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. B n = 8 B n = 4 B n = 12
