## Input file related changes
|
|
|
|
|
|
* OPAL-T: Beamlines containing a cathode have to have a `SOURCE` element to indicate this fact.
|
|
|
* OPAL-T: The design energy of dipoles is now expected in MeV instead of eV
|
|
|
* The meaning of `OFFSETZ` of the command `DISTRIBUTION` has changed. It now indicates a shift of the particle bunch relative to the reference particle. Use the `ZSTART` attribute of the `TRACK` command to start the simulation at a position `z > 0`
|
|
|
* The attribute `DISTRIBUTION` of the command `DISTRIBUTION` has been renamed to `TYPE`
|
|
|
* OPAL-T: The attribute `ROTATION` of `RBEND` and `SBEND` has been replaced by `PSI` which now can be applied to all elements to rotate them about the reference trajectory

## Input file related changes introduced in [OPAL-1.6](OPAL-1.6)
|
|
|
|
|
|
* The attribute `BFREQ` of the `BEAM` command is now in MHz instead of Hz
|
|
|
* Input files must have a version tag, for example
|
|
|
```
|
|
|
OPTION, VERSION=10900;
|
|
|
OPTION, VERSION=20000;
|
|
|
```
|
|
|
indicating version 1.9.x and newer
|
|
|
indicating version 2.0.x and newer
|
|
|
* OPAL is now fully typed. Each variable has to have a type for example
|
|
|
```
|
|
|
REAL Edes=.072;
|
|
|
REAL gamma=(Edes+PMASS)/PMASS;
|
|
|
```
|
|
|
Only **REAL, REAL CONSTANT, REAL VARIABLE, STRING, STRING CONSTANT, BOOL, BOOL CONSTANT** and **REAL VECTOR** are supported
|
|
|
* OPAL-T: Beamlines containing a cathod have to have a `SOURCE` element to indicate this fact.
|
|
|
* OPAL-T: The design energy of dipoles is now expected in MeV instead of eV
|
|
|
* The meaning of `OFFSETZ` of the command `DISTRIBUTION` has changed. It now indicates a shift of the particle bunch relative to the reference particle. Use the `ZSTART` attribute of the `TRACK` command to start the simulation at a position `z > 0`
|
|
|
* The attribute `DISTRIBUTION` of the command `DISTRIBUTION` has been renamed to `TYPE`
|
|
|
* OPAL-T: The attribute `ROTATION` of `RBEND` and `SBEND` has been replaced by `PSI` which now can be applied to all elements to rotate them about the reference trajectory
