The us­abil­i­ty of con­ven­tion­al BPM topolo­gies in com­pact lin­ear ac­cel­er­a­tors used for med­i­cal and in­dus­tri­al ap­pli­ca­tions is very lim­it­ed due to tight space re­stric­tions in such sys­tems. To over­come these lim­i­ta­tions, a dif­fer­ent ap­proach is in­tro­duced which is based on in­te­grat­ing the pick­ups into low-field re­gions of the ac­cel­er­at­ing struc­ture and eval­u­at­ing high­er beam har­mon­ics. Ap­pli­ca­tions based on this ap­proach will re­quire RF fron­tends in fre­quen­cy ranges be­yond those cov­ered by BPM ded­i­cat­ed hard­ware which is cur­rent­ly com­mer­cial­ly avail­able. There­fore, a demon­stra­tor setup is pre­sent­ed which is ca­pa­ble of in­ves­ti­gat­ing suit­able RF fron­tends for the pro­posed method. The demon­stra­tor uses ca­pac­i­tive pick­ups of the but­ton type for dis­place­ment sens­ing and al­lows for con­trol of the beam po­si­tion with the help of feed­back steer­ing coils which are typ­i­cal­ly used for com­pact linacs. Rep­re­sen­ta­tive sen­si­tiv­i­ty mea­sure­ment re­sults based on the eval­u­a­tion of the 2nd S-Band beam har­mon­ic are also pre­sent­ed in this paper.
