PREFACE

Here we publish the 22nd volurne of Surnmaries of Researches Using AMS at Nagoya
University. πle new volurne contains partly the proceedings of the 23rd Symposiurn on Chronologica1
Studies at the Nagoya University C없ter for Chronologica1 Research, held on January 13th_14 th, 2011 ,and includes a1so the sumrnaries of scientific research works performed by the domestic users at CCR
In this y않r， the s때rting year of the second term of “뼈dterm 0버 ectives and Plans", werefreshed our minds to take part in the program of satis함ing the duties as one ofthe Inter-D맹artmen때
Education 없d Res않rch Centers. 0따 two unique age-m않surement sys따ns， Tandetron AMS and

CHIME facilities , have been opera때 fully and s없dily to fulfill the 0뱅뼈lrol않 in this y없r. In thisway, scientific research works progressed well and in the symposiurn this y없r three specia1 lectures,
two status reports, research sumrnaries by two postdoctora1 research fellows , 21 reports by the users1名古옳*￥1J~ìl훌뚫質률分析計業&~告톨 , XXII .201 1. 03

were presented. In addition, 5 contributed papers are added in the 22nd volurne of Surnmaries ofResearches Using AMS at Nagoya University. It is rea11y encouraging us that severa1 papers wereprese뼈d by young students.
ndFifteen ye따s have passed since the 2=
Tandetron AMS system had been insta11ed at theCenter for Chronologica1 Rese따ch， and we have encountered con따1뻐lly several disord하s with the, though it is still pr때ucing a lot of impor때nt and useful age data constantly. It may
not easy to renew the rnachine immediately, owing to the rather bad economic situation of presentJapan. However, we shou1d ste때ily tak:e a step forward by fulfilling the research p빼s， to possibly
mac비ne recently

introduce the 3며 AMS machine at our 야nter. Since steady advance is going on in the age-meas따없nentres없rch， we must show our responsibilities by dεveloping the new methods in age-measurement

techniques and improving the existing rnachines , but a1so by enco따a밍ng young scientists who will beprominent learuπs of this field in future. He따ty support and collaborations are requested to 허1 related
researcn안s in and out of Nagoya University to make up the cent앉 that promotes the hi방1않t level ofchronologica1 research and education.
