FUNCTION

To keep your equipment where

required, as long as required

REQUIREMENTSTo detail and to add to the previous: To allow alignment to required position with

required accuracy To retain in this position as long as required To allow removal of smaller magnets without

breaking the vacuum To allow thermal expansion due to bake-out,

where applicable No effect to magnetic elements > non-magnetic

materials

ADJUSTABILITY

TABLES: X = ±15 mm; Y = ±15 mm; Z = +15 mm / - 52 mm Z-down by 52 mm allows to remove magnets without breaking

vacuum HIGHEST REQUIRED POSITIONING TOLERANCE:

X = ±0.2 mm(±0.1 Scrapers) Y = ± 1 mm(Scrapers ?) PLEASE

COMMENT! Z = ±0.2 mm(±0.1 Scrapers)

REGULATION: MOST COARSE REGULATION = 1.5 mm / TURN ON THREAD

BASED ALIGNMENT -> ~ 45 DEGREES FOR 0.2 mm
