Section: claims

1. A waveguide liner for an analyzer magnet chamber having three interlocking pieces of graphite, said liners having sufficient size to allow them to stand freely without being secured. 2. A waveguide liner as claimed in claim 1 wherein the three pieces are of uniform construction enabling said pieces to be interchanged. 3. A waveguide liner as claimed in claim 2 wherein each said piece includes a hole, said hole facilitating ease of installation and removal. 4. A waveguide liner as claimed in claim 2 wherein each said piece includes a pair of substantially parallel longitudinal groves at the rear of said liner, said gloves spaced and sized to accommodate retaining cables of a Kestrel analyzer magnet chamber. 5. A waveguide liner as claimed in claim 2 wherein each said piece at each end includes an overlapping portion. 6. A waveguide liner as claimed in claim 5 wherein at a first end said overlapping portion is a cut out at the front, and at said second end said overlapping portion is a cut out at the rear, said cut outs of said adjacent pieces being arranged to overlap. 7. A waveguide liner as claimed in claim 1 wherein each said piece includes a hole, said hole facilitating ease of installation and removal. 8. A waveguide liner as claimed in claim 7 wherein each said piece includes a pair of substantially parallel longitudinal groves at the rear of said liner, said gloves spaced and sized to accommodate retaining cables of a Kestrel analyzer magnet chamber. 9. A waveguide liner as claimed in claim 7 wherein each said piece at each end includes an overlapping portion. 10. A waveguide liner as claimed in claim 9 wherein at a first end said overlapping portion is a cut out at the front, and at said second end said overlapping portion is a cut out at the rear, said cut outs of said adjacent pieces being arranged to overlap. 11. A waveguide liner as claimed in claim 1 wherein each said piece includes a pair of substantially parallel longitudinal groves at the rear of said liner, said gloves spaced and sized to accommodate retaining cables of a Kestrel analyzer magnet chamber. 12. A waveguide liner as claimed in claim 11 wherein each said piece at each end includes an overlapping portion. 13. A waveguide liner as claimed in claim 12 wherein at a first end said overlapping portion is a cut out at the front, and at said second end said overlapping portion is a cut out at the rear, said cut outs of said adjacent pieces being arranged to overlap. 14. A waveguide liner as claimed in claim 1 wherein each said piece at each end includes an overlapping portion. 15. A waveguide liner as claimed in claim 14 wherein at a first end said overlapping portion is a cut out at the front, and at said second end said overlapping portion is a cut out at the rear, said cut outs of said adjacent pieces being arranged to overlap.
