  The TRI­UMF Ion Source and In­jec­tion Sys­tem (ISIS) beam­line is used to trans­port the 300 keV H− beam from the ion source to the in­jec­tion into the 500 MeV cy­clotron. The ver­ti­cal sec­tion of the beam­line, up­graded in 2011, is very ro­bust and re­li­able, while the hor­i­zon­tal sec­tion, now 50 years old, is very de­mand­ing in main­te­nance, and pre­sents a high risk of down­time due to aging. The hor­i­zon­tal beam­line is being re-de­signed with well proven op­ti­cal con­cepts, and mod­ern UHV tech­nolo­gies al­ready used in the ver­ti­cal sec­tion, and in the ARIEL RIB trans­port sys­tem; this will pro­duce a more ef­fi­cient sys­tem, eas­ier to main­tain and tune. The beam­line will use elec­tro­sta­tic op­ti­cal mod­ules like match­ing, pe­ri­odic, and 90-de­gree achro­matic bend sec­tions; up­dated el­e­ments in­clude bunch­ers, a high-en­ergy pulser, a 5:1 se­lec­tor, and a new set of di­ag­nos­tics. A cru­cial as­pect of the new beam­line is a mag­netic shield, to com­pen­sate the cy­clotron stray field, com­prised of a mu-metal in-vac­uum liner al­low­ing HV feedthroughs and di­ag­nos­tics in­ser­tion with­out break­ing the shield con­ti­nu­ity. The new in­jec­tion beam­line will be con­trolled via EPICS. The paper will pre­sent the sta­tus of the pro­ject.

  New neu­tron sources are needed both for Canada and in­ter­na­tion­ally as ac­cess to re­ac­tor based neu­trons shrinks. Com­pact Ac­cel­er­a­tor-based Neu­tron Sources (CANS) offer the pos­si­bil­ity of an in­tense source of pulsed neu­trons with a cap­i­tal cost sig­nif­i­cantly lower than spal­la­tion sources. In an ef­fort to close the neu­tron gap in Canada a pro­to­type, Cana­dian com­pact ac­cel­er­a­tor-based neu­tron source (PC-CANS) is pro­posed for in­stal­la­tion at the Uni­ver­sity of Wind­sor. The PC-CANS is en­vis­aged to serve two neu­tron sci­ence in­stru­ments, a boron neu­tron cap­ture ther­apy (BNCT) sta­tion and a beam­line for flu­o­rine-18 ra­dioiso­tope pro­duc­tion for positron emis­sion to­mog­ra­phy (PET). To serve these di­verse ap­pli­ca­tions of neu­tron beams, a lin­ear ac­cel­er­a­tor so­lu­tion is se­lected, that will pro­vide 10 MeV pro­tons with a peak cur­rent of 10 mA within a 5% duty cycle. The ac­cel­er­a­tor is based on an RFQ and DTL with a post-DTL pulsed kicker sys­tem to si­mul­ta­ne­ously de­liver macro-pulses to each end-sta­tion. Sev­eral choices of Linac tech­nol­ogy are being con­sid­ered and a com­par­i­son of the choices will be pre­sented.
