Abstract: An ion implantation system including an ion source for generating an ion beam, an end station for holding a substrate to be implanted by the ion beam, and a linear accelerator disposed between the ion source and the end station and adapted to accelerate the ion beam, the linear accelerator including at least one acceleration stage including a resonator and a resonator coil disposed within a resonator chamber, wherein the resonator coil is a tubular body having a plurality of coaxial layers, including an inner layer, a middle layer, and an outer layer, wherein the outer layer is formed of a dielectric material.

Abstract: Uncollected tax liens are made collateral for a loan to a public authority who buys the tax liens from the taxing district. The public authority assigns its right to receive monies obtained through the normal collections/property sale channels by the taxing district to the lender to payoff the outstanding note. Collection procedures remain unchanged except that the taxing district forwards receipts to the lender in satisfaction of the debt. Any questionable collections can be devalued/exempted from the total and up to 103% of the basis amount loaned to the taxing district. The taxing district agrees to repurchase unredeemed claims after a fixed period. The loan can be renewed annually by substituting the most recent year's liens for the oldest year's to re-figure the basis. An optional re-acquisition provision is included enabling the taxing district to repurchase of unpaid liens for 10% of face value, once the lender has been repaid.
