Files present here: UCNSD2v12.doc the LANL SD2 and UCNA technical design report. AsBuiltToGV2.ppt and .txt are Roger Hill's final simulations of our source. After this point, the work was transferred over to NCSU grad student Yan-Ping Xu, who completed his PhD thesis on these type of simulations, but for the NCSU reactor UCN source. NIC_SD2.txt and NIC_SD2.nb and ColdFlux.txt are Roger Hill's information on how the UCN optimization was carried out using his computer simulations, including some details of MCNP etc. construction.gif is an old, but somewhat interesting, UCNA management plan. UCN_Construction_Issues.doc an interesting task list showing some details of the progress towards the realization of UCNA. initial_rsc_pres.ppt is a presentation from a LANL staff person (Kelsey?) on the evaluation of the radiation shielding for the source and of the cooling of the target. ucn_final_PLANVIEW.dwg is the drawing used to assemble the source and shielding. ucnlayoutBASELINE.ppt is a discussion document from Andy Saunders summarizing, I think, the initial_rsc_pres.ppt, after or as construction was being completed.
