| 1 | MedAustron beam time structure: from HT Lau 21Jun19 |
|---|
| 2 | =================================================== |
|---|
| 3 | |
|---|
| 4 | * Typical beam spill for protons: 5 seconds |
|---|
| 5 | * Typical beam spill for carbon: 4 seconds |
|---|
| 6 | |
|---|
| 7 | * Average time between spills: 2 seconds |
|---|
| 8 | * Minimum time between spills: 1 seconds |
|---|

| 11 | Proton time structure: |
|---|
| 12 | ---------------------- |
|---|
| 13 | |
|---|
| 14 | Beam on -- 5s |
|---|
| 15 | +----------------------+ +------------- |
|---|
| 16 | | | | |
|---|
| 17 | --------+ +-------------+ |
|---|
| 18 | Beam off |
|---|
| 19 | 1-2 s |
|---|
| 20 | So: |
|---|
| 21 | * Period (T) of beam delivery for protons: T = 6s --- minimum |
|---|
| 22 | = 7s --- average |
|---|
| 23 | |
|---|
| 24 | Carbon time structure: |
|---|
| 25 | ---------------------- |
|---|
| 26 | |
|---|
| 27 | Beam on -- 4s |
|---|
| 28 | +----------------------+ +------------- |
|---|
| 29 | | | | |
|---|
| 30 | --------+ +-------------+ |
|---|
| 31 | Beam off |
|---|
| 32 | 1-2 s |
|---|
| 33 | So: |
|---|
| 34 | * Period (T) of beam delivery for carbons: T = 5s --- minimum |
|---|
| 35 | = 6s --- average |
|---|
| 36 | |
|---|
| 37 | Time structure within beam spill: |
|---|
| 38 | --------------------------------- |
|---|
| 39 | |
|---|
| 40 | * Debunching follosed by slow extraction ensures that beam within |
|---|
| 41 | spill is 'DC'. |
|---|
| 42 | |
|---|
| 43 | * We should assume for the moment the rate is flat over the spill. |
