You are defining a proton beam with energy 100MeV but with momentum spread WHAT(2) Dp(FWHM)=2.355 GeV! Change the Dp to 0 and you will a value close to Herrera et al paper. Vasilis df_masithoh wrote:dear FLUKA users I have simulated spallation reaction of thick Hg target with various proton energi in range 100 MeV - 1000 MeV. Some of them (100 MeV - 300 MeV)are attached. I want to know about the neutron yield. I read at "Accelerator Driven System Design FLUKA Exercise, ICTP Lecture" by Herrera Martinez and Yacine Kadi that it can be extracted from file_name00x.out But what i get from the file is : neutron yield for 100 MeV proton is 1.1xx E+01, 1.2xxE+01 for 200 MeV. (Too much higher isn't it?) And I get 2.9xx E+01 for 1000 MeV proton. (i think it's approach Herrera&Kadi result in their paper). Can you tell me what i did wrong? Any respons will be greatly appreciated. Thank you--------------030703070701010903030006 Content-Type: text/x-vcard; charset="utf-8"; name="Vasilis_Vlachoudis.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="Vasilis_Vlachoudis.vcf" begin:vcard fn:Vasilis Vlachoudis n:Vlachoudis;Vasilis org:CERN;AB adr:CERN;;Dep.AB;Geneva-23;;CH-1211;Switzerland email;internet:Vasilis.Vlachoudis@cern.ch title:Dr tel;work:+41-22-767.9851 tel;fax:+41-22-766.9644 tel;cell:+41-76-487.4378 x-mozilla-html:FALSE url:http://home.cern.ch/bnv version:2.1 end:vcard --------------030703070701010903030006--
