RE: [fluka-discuss]: Recombination of electron and ion pairs in ionizing chamber

Dear Bo Yang,
FLUKA is not able to simulate directly the recombination process. However, recombination can be taken into account applying a correction to the deposited energy. By activating the TCQUENCH card, energy depositions are corrected as a function of dE/dx according to the Birks formula. The user must provide Birks parameters relevant for the specific medium and electric field.

Dear Bo Yang,

FLUKA cannot simulate recombination of electron and ions pairs in ionizing chambers. However, it is possible to make a correction to the energy deposited, as you can see in the attached Note. See in particular Sec. 5

Subject: [fluka-discuss]: Recombination of electron and ion pairs in ionizing chamber

Dear Fluka users,

   I would like to evaluate the effects of recombination of electron and ions pairs in ionizing chamber generated by photon with the utrashort time scale of ps (1.0E-9s).I try to use FLUKA to smiulate this process,but encounter some questions as followed.

     (1) I don't know if Fluka could provide a static electric field as that in ionizing chamber.If not, Is there any other simulation code suggested ?

     (2) I doubt that if FLuka could simulate the process of recombination of electron and ions pairs,Beacause I want to evaluate the underestimation due to recombination of electron and ions pairs in ionizing chamber .

  I know these requirements might be beyond the capabilites of FLUKA.I just want to some suggestions from everyone so that I could solve above questions. Any help will be really appreciated. Thanks in advance.



BO YANG
