Dear friends,

New release Mokka 6.6.p01 is available for download at the usual address:

Please note that the last two LDC/LDCPrime models have been
renamed to LDC01_06Sc and LDCPrime_02Sc and their status was set
to 'frozen'.


From Release Notes:

============================================================ ==
New tag mokka-06-06-p01

What is new in this Mokka release

I. New steering commands available to change FieldManager parameters

II. New FTD self scaling FTD Driver SFtd03

============================================================ ===================

Please note that:

1. This Mokka release co-works with Geant4 9.1.p02 and CLHEP
(but it is still compatible with previous Geant4 / CLHEP versions)
LCIO v01-05, v01-06, v01-07, v01-08-01 or v01-09 (recommended),
gcc 3.2.3, gcc 3.4.5 or
gcc 4.1.1, SL3 or SL4, optionally with Gear v00-08-02

============================================================ ===================

I. New steering commands available to change FieldManager parameters

Two new steering commands were implemented to change the parameters
DeltaIntersection and DeltaOneStep of the FieldManager:
They can be used in the steering file, like, for example:

/Mokka/init/userDeltaIntersection 3e-5 mm
/Mokka/init/userDeltaOneStep 3e-4 mm

II. New FTD self scaling FTD Driver SFtd03

It is a self scaling driver where the z positions of the disks are set
relative to the length of the TPC and the inner radius of the disks are
calculated as a function of the beamtube opening angle.
The TUBE_opening_angle is used, though this does not affect the actual
beam tube in Mokka, as that does not take this value as a parameter,
nor does it attempt to set it. The actual opening angle of the section
of the beam tube lying directly under the FTD in the Mokka model
LDC01_06Sc has a tangent of 0.07876. As the value of TUBE_opening_angle
will be set to 0.092 the FTD will not suffer any geometric overlap with
the beam tube and the inner radii will be of the desired size, not a
great solution but at least safe for now.

There are values for cable shield thickness, cable thickness and
outer support cylinder thickness in the Database.
