フィルター（QM1）でサイズを選ぶ。このようにして、原子１個の精度でサイズが定まったクラスタ
ーを取り出す。
生成されたクラスターの質量スペクトルの一例を図 3 に示す。
これは銀クラスター正イオン（AgN+）の例であり、原子数 147 個以上のクラスターの生成が確認されている。因みに Ag147+の直径は約 1.7 nmであり、単独の原子からいわゆるナノ粒子まで、原子１個の精度で目的のクラスターを生成することができる点で、これからのナノ科学技術において重要な実験技術に位置づけられる。なお、この例では質量分布の極大が N = 30 付近だが、He ガスや Ar イオンの流量によってサイズ分布をある程度制御することができる。また、スパッタ室を冷却しない場合には、生成種の大半は単量体の原子もしくはイオンであり、クラスターはほとんど成長しない。
