1. R-D Herzberg The SAGE Spectrometer The next four years

2. R-D Herzberg Overview Brief Physics Case Technical description Work to be done

3. R-D Herzberg Physics In heavy nuclei Gamma rays and conversion electrons compete. E.g. for Z~100: E2: Conversion is dominant above 400 keV M1: Conversion is dominant above 200 keV

4. R-D Herzberg Physics Any heavy (trans-)actinide nucleus must be studied twice: gammas and electrons SAGE allows the simultaneous investigation of gamma rays and conversion electrons in the same experiment!

5. R-D Herzberg Why us? We’ve done Juroshpere/gam Dito SACRED Dito GREAT Dito TDR Dito a lot of heavy element work A lot of experience and expertise is collected in this room!

6. R-D Herzberg Ingredients Ge – Array John, Pete Solenoid Paul, Juha Si – detector Rodi, Robert Electronics Ian, Jim, Patrick, Dave Mechanics Dave Software John, Simon, Vic

7. R-D Herzberg Technical details

8. R-D Herzberg Ge array What shape do we want Jurogam to take in the future? As is? Clovers?

9. R-D Herzberg Solenoid Need to efficiently transport the electrons from the target to the detector Must not interfere with Ge detectors Tricky: need optimisation

10. R-D Herzberg Si detector High pixellation Rate distribution High rate capability

11. R-D Herzberg Electronics DIGITAL TNT2 tests have been done Total capability up by a factor 12: 4 x segmentation, 3 x rate/pixel Huge data rates!

12. R-D Herzberg Mechanics Target chamber Solenoid support Si detector chamber Ge frame Target wheel Windowless operation?
