The Los Alamos Neu­tron Sci­ence Cen­ter (LAN­SCE) lin­ear ac­cel­er­a­tor dri­ves five user fa­cil­i­ties: Iso­tope Pro­duc­tion, Pro­ton Ra­di­og­ra­phy, Ul­tra-Cold Neu­trons, Weapons Neu­tron Re­search, and Neu­tron Scat­ter­ing. In 2011, we started an am­bi­tious pro­ject to re­fur­bish key el­e­ments of the LAN­SCE ac­cel­er­a­tor that have be­come ob­so­lete or were near end-of-life. The con­trol sys­tem went through an up­grade process that af­fected dif­fer­ent areas of LAN­SCE. Many im­prove­ments have been made but fund­ing chal­lenges and LAN­SCE op­er­a­tional com­mit­ments have de­layed pro­ject de­liv­er­ables. In this paper, we will dis­cuss our up­grade choices, what we have ac­com­plished so far, what we have learned about up­grad­ing the ex­ist­ing con­trol sys­tem and what chal­lenges we still face.

Los Alamos Na­tional Lab­o­ra­tory has de­fined a new sig­na­ture sci­ence fa­cil­ity, Mat­ter-Ra­di­a­tion In­ter­ac­tions in Ex­tremes (MaRIE) that builds on the ex­ist­ing ca­pa­bil­i­ties of the Los Alamos Neu­tron Sci­ence Cen­ter (LAN­SCE). It will be the first multi-probe ma­te­ri­als re­search cen­ter to com­bine high-en­ergy, high-rep­e­ti­tion-rate, co­her­ent x-rays with elec­tron and pro­ton-beam charged-par­ti­cle imag­ing to per­form in-situ mea­sure­ments of a sam­ple in ex­treme en­vi­ron­ments. At its core, a 42-keV XFEL will be cou­pled with the LAN­SCE MW pro­ton ac­cel­er­a­tor. A pre-con­cep­tual de­sign for MaRIE has been es­tab­lished. Tech­ni­cal risk re­duc­tion for the pro­ject in­cludes an in­jec­tor test-stand that is cur­rently being de­signed. New ac­cel­er­a­tors are ei­ther planned, under con­struc­tion, or cur­rently in op­er­a­tion around the world, pro­vid­ing op­por­tu­ni­ties for the MaRIE pro­ject to lever­age the in­stru­men­ta­tion & con­trols (I&C) ef­forts of these fa­cil­i­ties to min­i­mize non-re­cur­ring en­gi­neer­ing costs. This paper dis­cusses pos­si­ble MaRIE I&C sys­tem im­ple­men­ta­tion choices and trade-offs, and also pro­vides an overview of the pro­posed MaRIE fa­cil­i­ties and the cur­rent de­sign.
