| Activity | People | Description |

| Modeling Cyclotron Extraction | Rao, Baartman | Discovered an error in
code used to track beams from stripper to beamline. This affects
all primary beamlines. Can now successfully model the beam. (EOM) |
| 2A Halo | Rao, Baartman, Root, Doornbos | Need to transport up to
100 mA with < 1nA/metre loss. This requires understanding at the
< 10-5 level. (foil, gas, ...) |
| 2A stability during 1A/2A running | Root, Rao | RIB production targets are
fragile, so need tight tolerance. Beam on stripper is only about 1mm
wide, so shaking the orbit centre by 100 mm already causes
difficulties. Feedback technique results. |
| Intensity Limitations of the TRIUMF Cyclotron | Root, Baartman | Eventually,
we would like to run reliably at 400 mA total beam. There is a
space charge limit at injection of about 10 mA per degree of phase
acceptance. Exceedingly difficult to simulate. Experiment. |
| Detailed understanding of Inflector Matching | Baartman, Root | Need a spare inflector, need a new vertical section for ISIS. |
| Cyclotron Operator Training | Root | Betatron motion, isochronism, beam plane steering with trim and harmonic
coils, etc. |
| ISAC Operator Training | Baartman | Quads, Benders, Slits, Steerers (talk) |
| On-line optics models | Baartman | For training, demos, investigating and
developing new tunes. ENVtk |
| ISAC beamline design | Baartman, Kaltchev | Currently: TITAN, ISAC-2 experimental hall, CSB, EMMA. |
| Secondary beamline design/upgrade | Doornbos | M9, M20 |
| ISAC-3 ideas | Craddock, Kaltchev | Possible accelerator/storage ring for RIBs |
| Activity | People | Description |

| ILC | Koscielniak | Design of damping ring. GDE Workshop here this summer. |
| J-PARC | Koscielniak | Design of transverse damper (just getting started). |
| Secondary beam channels at J-PARC | Doornbos | Kaons, decay muons, surface muons. |
| CIAE | Rao, Baartman | Design 70 MeV cyclotron |
| D-Pace, THALES | Rao,
Baartman | Design/upgrade cyclotrons by contract (100k$ net so far). |
| GEANT4 | Jones | |
| LHC Collimators | Kaltchev | Design work is completed, but commissioning
work may come our way. |
| LHC tracking | Kaltchev | (1)With field errors in the IR1 (ATLAS) and IR5
(CMS) triplet quadrupoles, triplet correctors and coupling correctors;
(2)with low order errors, orbit correction and beta-star correction (at
the IP). Uses LHC@home. Tune scan. |
| Coherent Beam-Beam in LHC | Jones | Using ACCSIM and HFM. Needs access
to a massively-parallel system in Europe, and will likely also
utilize Westgrid's facilities. |
| b-Beam neutrino factory study (CERN/Eurisol) | Jones,
Baartman | General layout,
simulations of the decay ring (6He2+®6Li3+) |
| Activity | People | Description |
|---|
| Lepton and Hadron Acceleration in FFAGs | Koscielniak, Craddock | Design of 2.5-20 GeV FFAG accelerators
for a muon collider or neutrino factory, and initial plans
for a 10-20 MeV electron demonstration model of such
machines. Application for NSERC special grant (30k$/yr for 3 yrs). |
| LieMath | Kaltchev | New technique of using Lie algebraic methods and
Mathematica to calculate high order maps. |
| Fringe Field Effects | Baartman | Developing simpler calculational
techniques based in Canonical transformations. (old talk) |
| Space Charge Code Benchmarking | Jones | A collaboration of accelerator physicists has been formed
to compare, benchmark, and validate codes for
simulation of space-charge effects in synchrotrons and
storage rings. There are seven codes and laboratories involved.
ACCSIM (TRIUMF), IMPACT (LBNL), MICROMAP (GSI),
ORBIT (SNS), SIMBAD (BNL), SIMPSONS (KEK), and SYNERGIA (FNAL).
The initiative is motivated by the need to raise confidence
in predictions of beam loss and quality for mega-watt beam projects
such as SNS and J-PARC, and to explain observations and
possibly improve the performance of existing high-intensity
machines. |
