Query: Finite Elements Magnetic Analysis of the CLIC MDI Region   Considering the current CLIC SiD detector design and the machine parameter
L*, the final focus quadrupole QD0 will be placed inside the experiment itself.
This configuration is very challenging from an integration point of view. Among
several other aspects, the iron-dominated QD0 will need an active magnetic
shielding to avoid undesired interactions with the magnetic field generated by
the main solenoid of the detector. This shielding will be provided by a
superconducting anti-solenoid, and this paper aims to describe the method used
to design such device, the results obtained and the issues still to be solved.
