2. MICE Coordinate System: Definition ISIS ring (Y = 0 mm) (0,0,0) Z MICE Target (X T, Y T, Z T ) MICE Beam Axis (X B, Y T ) Centre of ISIS accelerator ring at the beam level MICE Apparatus MICE Reference Point (X M, Y M, Z M ) Centre of ISIS ring (0, 0, 0) MICE target (X T, Y T, Z T ) MICE beam axis (X B, Y B ) MICE apparatus reference point (X M, Y M, Z M ) Coordinate system: centre is located in the centre of ISIS ring at the beam level axis Z is parallel to the MICE beam axis axis Y is vertical X

3. MICE Stages

4. Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 MICE Reference Point & MICE Stages Reference point = Centre of the central absorber

5. Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 MICE Reference Point & MICE Stages (2) Reference point = Beam diffuser

6. MICE Reference Point & MICE Stages (3) Where do you think a MICE reference point should be located ?
