Kurt. J. Lesker Company offers the PA35-H adjustable bellows with adjustability of +/-5mm axially and +/-3 degrees at a price of $1,423 . Due to the budget constraints and problem statement of simply getting a spectrum, a cheaper alternative is desirable . Through a finite element analysis, it has been determined that compressing a CF flange copper gasket using asymmetrical torque of clamping hardware will allow the primary ion impact location sufficient adjustability to meet the 50-micrometer alignment tolerance. A cross section of the CF flange can be seen in Fig. 21. Figure 21: Cross section of a CF flange with copper gasket that is deformed to create a seal
