Proceedings of the 1st Annual Meeting of Particle Accelerator Society of Japan and the 29th Linear Accelerator Meeting in Japan (August 4 - 6, 2004, Funabashi Japan) Cavity Performance of 972MHz 9-cell Niobium Cavities for Proton Superconducting LINACG A) K.Saito1,A), H.InoueA), T.HiguchiB) High Energy Accelerator Research Organization (KEK), 1-1 Oho, Tsukuba-shi, Ibaraki-ken, 305-0801, Japan B) Nomura Plating Ltd. Co., 20-12-5 Himejima, Nishiyodogawa-ku, Osaka-shi, 555-0033, Japan Abstract Currently we are prototyping a 972MHz superconducting RF cryomodlue, of which object is to demonstrate the key technology for ADS (accelerator driven system). KEK has been commissioned to fabricate some risky cavity parts for industrial production, and to make surface preparation and evaluate the cavity performance. In this paper these results are reported. ȋ Ł Ƴ ƿ NJ ° ȉ 972MHz-9ȗ ȗ¡ĄNjmžǙ A&BjȈƈžmȒRµĴi¬~Ƅĵ `{\jl^c:ĄNjÀƽư9ðØųLjŽęmcu ĕij9ǓǼĒ ŁȔĎúť nDzǭÏâ òŠũměǸ l>©¢~Ô^hÜUyĄNjlȔ~ÍTǵć ĎúCáŴƼ ĒŁȔ ©mòŠÛ ǠDm¾> ~ȆT{:¤>¢²>Vřǰĩž~Ȅ^kRj §j ^ hC Í ƛí Ă LjÞ ǵ ç © m òŠ Û Ǡ bmȔnb\l÷Ŕ]|h^rS:řǰkĩžßǷ džD~ĦfhR{:dzſ @ ǗmJǗĉÓiQ{: mcul&¢AL 3Blǒ Ğ --mµ°µ ÍƛímĎ ún9Ē ĎVŹŷ `{!A ''(,(1%3/1 ~ ǀ Ł > ©Ȉ ƈ ^9 b |~ Í ġ^ h ¤> ¢ 1+4(. !623(- Bm ȊƑ òŠ mß Ȏm cu l9Ƴƿ ²>~Ƅĵ`{ņl^c:ŸHl9bmƬǿŸV NJȋŁÍƛ ©~Ņ ĵ`{\jl Q{:HBŸ Ŋ]|hR{:ĞǒµmȈƈi&¢lȅ Ɠ HlŊ`P ȗ¡Ƴ ƿNJĄNjA b B~Ǒƣ9 Ümǖșs~ Ƃ_9bm Ŗƀmcul¤>¢²> IBb|~Ŕ ǘ`{Ç ¯ ~Ƅĵ^9 mǐ ĈV Ɖĉ ƭxz9 --ƺDŽ ƤW Yk fh ^ JB¯ «> ±im+)* /5(1 ~Ħ rfcV9ŝġmDZLJlxzǾņĄNjlȈƈiWc: S:ĄNjj ¯ nĸǤŝ ġ;ŶėƘƍ ¦EǫW>©¢ ťiƄĵ^c :Ò=nĒ ĎUym¼Ƨ Ďúj^h9 IÀƽin9 mŮĪ lǡqƭ V ǜºŭĨ ĄNjmƄĵl ì^9òŠ Ƽ°mƤ WRĄNjìȗ Y9ĄNj~¯«>±lƒĬtı9ĄNj ǐ ǭǩmƄĵ9 ĄNjmǧǿ ţȍjŜžǙ Ņđlx{Ą ǧǿmÄƋV žǙȖËl Ʊ^RÁÿ~ vcy`:Ś NjžǙǨÌ~ ƅZǬfc :Ǽǹīin 9b|ymČ ȌŵĄ>±lľȉ^hȌcµ©n9ýY Ð~ǹī`{: ¯µǿlY fǫW9ĄNjǰÕŇl ¯µǿlļ {:bmµ©mŦ ûĵĀưlµ©Ǜ Ƕ .KEK ! lx{ĄNjÄ ƋmÎǙžVQ{:^cVfh9> ±~xzĤžmQ{ǯl ƢT{ǥȊVQ{:ÈǴ i H ¤>¢²> n9±¨Īā~ľRŀ uhR{:\mŮĪ9 ¯ ǼƳƿNJĄ NjmŕǚŻ n 7iQ{ :ĄNjmÀ µmĤDŽV Ȋù]|{:& ¯µn9ĨŢDŽË ƽnI i Ħ}| {: bmı 9ľ ȉÂƟ £°©ȓ Vŷs śy UÑ X{ AƸ &Ĵnȉǁ Vŧ kY 9 ~Ĕy`cu 9rc9Ƴ ȏLjÂƟ£° ©A Bm ª> >inƄƘ^kRB:^cVfh9ĨĤDŽ½ žŏUy9¦ >m ¯ µ>±ǭ n9ƳȏLj£ Ĵ ¯µ~¡ĄNjlƈĪ`{ǥ ȊVƂ_{ : °©lƷU ykR9` k}eŵĄƬ ǖƔǭlQ{ Ǽ č i n 9 & ¢ j µ ² ¢ xSl`{ņ džUy9Ą Njl£°© Ɣ~Ȉƈ^c A !"!
