В рамках експерименту DsTau на приcкорювачi SPS в ЦЕРНi нами запропоновано незалежний та прямий спосiб дослiдження продукування тау-нейтрино в високоенергетичних зiткненнях протонiв з ядрами. Зважаючи не те, що основним джерелом нейтрино є розпад Ds-мезонiв, в проектi будуть вимiрюватись диференцiйнi перерiзи цього процесу. Методика експерименту базується на застосуваннi емульсiйних детекторiв для ефективної реєстрацiї подiй розпаду короткоживучих частинок. Нами представлено мотивацiю проекту, деталi експериментальної технiки, а також першi результати аналiзу даних з перших пробних сеансiв, що показали ефективнiсть нашого експерименту.
