The Velocity Vector for Transport in a magnetic field is now set correctly.
|
|
--> previously the scalar velocity was automatically promoted to a 3-vector
|
|
|
|
Nov 25, 1998 J. Apostolakis
|
|
|
|
Added the direction to LocateGlobalPointAndUpdateTouchable.

|
|
Fixes:
|
|
|
|
1) The final energy is set equal to the initial energy, because
|
|
the PropagatorInField does not calculate it correctly yet. NEEDS Fix
|
|
|
|
2) If the requested step size is zero and safety is zero, the
|
|
step is now considered geometry limited. (This can happen
|
|
if a discrete process tries to take a step that is very small
|
|
compared to the mean free path.) Problem observed by Laszlo in EM tests.
|
|
|
|
3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity.
|
|
|
|

|
Changes to accomodate new interface of Field:
|
|
(G4PropagatorInField and G4FieldTrack. )
|
|
|
|

|
|
|
|
In the case of magnetic field, a flag that determines whether the
|
|
geometry limited the step was not set.

Checks whether the particle is out of the world volume
|
|
If so it has exited and must be killed.
|
|
|
|
|
|
Aug 28, 1998 J. Apostolakis
|
|
|
|
The PostStepGetPhysicalInteractionLength has fixed (to return kInf)
|
|
The boolean flags for touchables are now initialised. & Other small fixes ?
|
|
Test code for non-relocating case added (for debugging).

|
|
|
|
Corrected Safety computation for the case of the field (adding endpoint
|
|
distance instead of curve length.)
|
|
|
|
Added PostStepDoIt method that tries to relocate the particle using
|
|
G4ParticleChangeForTransport
|
|
|
|
Transportation is no longer a G4ContinuousProcess.
|
|
|
|

|
|
|
Modified it to recomputate Safety at the start of a step. To do this
|
|
it uses the previous step's calculated safety and endpoint.
|
|
|
|
|
|
June 08, 1998 J. Apostolakis (trans-06-02)
|
|
|
|
Modified it to add re-computation of Safety at the endpoint of a step,
|
|
when the safety would become negative. This is done to allow processes
|
|
to benefit from a realistic (geometrical) value of the safety. The
|
|
request to do this was from EM physics
|
|
|
|
|
|
June 03, 1998 J. Apostolakis (trans-06-01)
|
|
|
|
The safety we is now generalised to mean the limit of assumption of all
|
|
processes. The AlongStepGPIL input value is not the remainder from the
|
|
previous step's geometrical safety.
|
|
|
|
So the transportation must recalculate the starting point's safety here.
|
|
As a zeroeth order approximation we set it to zero.

April 17, 1998 M. Maire (recorded by John Apostolakis )
|
|
|
|
A new process, G4UserSpecialCuts, was added to allow the
|
|
user an alternative method to set some user cuts.
|
|
|
|
|
|
April 15, 1998 H. Kurasige (recorded by John Apostolakis )
|
|
|
|
The transportation does the absolute minimum required to conform to
|
|
the new scheme for ParticleChange: G4VParticleChange is used in signature.
|
|
[ But default G4ParticleChange is still used ].
|
|
